A. The **free energy** to the given problem is:ΔG = -1.1574 x 10^6 J/mol

B. The reaction is spontaneous.

A. Calculation of free energy change for the reaction at 35 °C

We know that

:ΔH∘rxn = -1269.8 kJ/mol,

T = 35 + 273 = 308 K, and

ΔS∘rxn = -364.6 J/K

At the **temperature** T, the free energy change (ΔG) for the reaction can be calculated using the following formula

:ΔG = ΔH - TΔS

Here, we have

:ΔG = (-1269.8 x 10^3 J/mol) - (308 K) (-364.6 J/K)ΔG

= -1269.8 x 10^3 + 112.38 x 10^3ΔG

= -1.1574 x 10^6 J/mol

The value of ΔG is negative, which means that the **reaction** is spontaneous at 35 °C.

B. Determination of spontaneity of reaction

The spontaneity of a reaction can be determined using the following equation:

ΔG = ΔH - TΔSIf ΔG < 0, then the reaction is spontaneous at the given temperature.

In the given case, we have:

ΔG = -1.1574 x 10^6 J/mol

Since ΔG is negative, the reaction is spontaneous at 35 °C.

Therefore, the answer to the given problem is:ΔG = -1.1574 x 10^6 J/mol

The reaction is **spontaneous**.

The question should be:

for a reaction with only one reactant, what is the minimum number of trials that will have to be done to gather sufficient initial rates data to be able to write the complete rate law?

A minimum of two trials are required to obtain sufficient initial rates data for a single reactant reaction to write the full **rate law**. A full rate law should be written once initial rates data have been collected for a single reactant reaction.

The full rate law describes the relationship between the rate of the reaction and the concentrations of the reactants as well as any catalysts. Furthermore, since only one **reactant** is involved, the reaction is referred to as a first-order reaction. When dealing with first-order reactions, the relationship between the rate constant and the half-life can be expressed as follows:t1/2 = 0.693/k = ln2/k where k is the rate constant and t1/2 is the half-life of the reaction.

The half-life is the length of time it takes for the initial concentration of a reactant to decrease to half of its original value. The time it takes for a first-order reaction to be complete is determined by the rate **constant,** which is specific to the reaction. Two or more trials are needed to obtain sufficient initial rates data for a single reactant reaction to write the complete rate law.

The **half-lives** are measured at different concentrations of reactant in these trials, and the data are utilized to compute the rate constant k. The rate constant k is then employed to create the complete rate law, which relates the rate of reaction to the concentration of the reactant(s) and any catalysts present.

The **proton's **acceleration is 6.23 × 10² m/s². The electric force between the **nucleus **and the proton can be calculated by Coulomb’s law.

The radius of the nucleus (r) is given as 6.0 fm. The **distance **between the nucleus and the proton is d = 6.0 + 3.0 = 9.0 fm.q₁ = charge on the proton = +e = +1.6 × 10^-19 Cq₂ = charge on the nucleus = +54e = +54 × 1.6 × 10^-19 Cq₁q₂ = +1.6 × 10^-19 × 54 × 1.6 × 10^-19 C²q₁q₂ = 1.741 × 10^-36 C²r = 9.0 fm = 9.0 × 10^-15 m

Now substituting these values in Coulomb’s law, we get:F = 9 × 10^9 × 1.741 × 10^-36/(9 × 10^-15)²F = 1.04 × 10^-25 NThus, the **electric **force on a proton 3.0 fm from the surface of the nucleus is 1.04 × 10^-25 N.Part BThe acceleration of the proton can be calculated using Newton's second law of **motion**, F = ma, where F is the force, m is the mass of the particle, and a is its acceleration.

In this case, we know the force acting on the proton (1.04 × 10^-25 N) and the mass of the proton (1.67 × 10^-27 kg).F = ma1.04 × 10^-25 = (1.67 × 10^-27)a∴ a = 6.23 × 10² N/kgThus, the proton's acceleration is 6.23 × 10² m/s².

The **energy** required to melt 200 kg of ice at 0°C is approximately 6.67×10⁴ kJ.

To calculate the energy required to melt ice, we use the formula:

Energy = mass × heat of fusion

Given:

**Mass** of ice = 200. kg

Heat of fusion (δHfus) for water = 6.01 kJ/mol

explain how t would be affected if a greater amount of surrounding solvent water is used assuming the mass of salt remains

**ΔT** will be affected in a way that it decreases if a greater amount of surrounding (solvent) water is used, assuming the** mass of salt** remains constant.

ΔT is directly proportional to the **molality (m)** of the solution.

ΔT = K f × m

Where K f is the **freezing point depression** constant and m is the molality of the solution (moles of solute per kilogram of solvent).

Molality (m) is inversely proportional to the **mass of solvent**.

m ∝ 1/mass of solvent

**The equilibrium constant **for the given reaction at 25 °c is approximately 11.54.

**What is the standard Gibbs free energy ?**

**The standard Gibbs free energy (ΔG°)** is a **thermodynamic** property that measures the maximum reversible work that can be obtained from a chemical reaction at standard conditions (usually at 25 °C or 298 K, 1 **atmosphere pressure**, and specified concentrations).

To calculate the equilibrium constant (K) for the given reaction at 25 °C, we need to use the standard Gibbs free energy change (ΔG°) and the relationship between ΔG° and K.

The equation relating ΔG° and K is as follows:

ΔG° = -RT ln(K)

Where:

ΔG° = the standard Gibbs free energy change (in joules/mol)

**R= the gas constant** (8.314 J/(mol·K))

**T= the temperature in Kelvin** (25 °C = 298 K)

K = the equilibrium constant

Given that the ΔG° of the reaction is -6.060 [tex]kJmol^{-1}[/tex], we need to convert it to joules:

ΔG° = -6.060 kJ/mol × 1000 J/kJ = -6060 J/mol

Plugging in the values into the equation:

-6060 J/mol = -8.314 J/(mol·K) × 298 K × ln(K)

Now, we can rearrange the equation to solve for ln(K):

ln(K) = -6060 J/mol / (-8.314 J/(mol·K) × 298 K)

ln(K) ≈ 2.446

Finally, we can calculate K by taking the exponential of both sides:

[tex]K = e^{ln(K)}\\= e^{2.446}[/tex]

K ≈ 11.54

Therefore, the equilibrium constant (K) for the given reaction at 25 °C is approximately 11.54.

The Gibbs **free **energy **change **is 1947 J/mol or approximately 1950 J/mol. Therefore, the answer is 1947 J.

The formula for calculating the Gibbs free **energy **(ΔG) of a reaction is:ΔG = -RT ln Kc, where,ΔG = Gibbs free energyR = gas constantT = temperature in KelvinKc = equilibrium constant

Here, given equilibrium constant kc = 9.1 × 10⁻⁶ at 298 KWe have to **calculate **ΔG at the same temperature.

Now, we need to calculate ΔG.Using the formula, ΔG = -RT ln Kc. Substituting the values, ΔG = - (8.314 × 298 × ln 9.1 × 10⁻⁶) = 51059 JWe know that Gibbs free **energy **is expressed in Joules (J).

Therefore, the Gibbs free energy (ΔG) is 51,059 J.However, we also have to consider the concentration of [Fe³⁺] = 0.368 M.

Now, the formula to calculate the Gibbs free energy change is:ΔG = ΔG° + RT ln Q,

Where,Q = reaction quotientΔG° = standard **Gibbs **free energy changeR = Gas constantT = TemperatureQ = { [Fe²⁺]² [Hg₂²⁺]² } / { [Fe³⁺]² [Hg₂₂⁺] }

The reaction stoichiometry is:2Fe³⁺ + Hg₂₂⁺ ⇌ 2Fe²⁺ + 2Hg₂²⁺

Initially, before the reaction begins, there are no products, hence,Q = { [Fe²⁺]² [Hg₂²⁺]² } / { [Fe³⁺]² [Hg₂₂⁺] } = {0} / { (0.368 M)² (0 M)²} = 0ΔG° = -RT ln Kc= -(8.314 J K⁻¹ mol⁻¹ × 298 K × ln (9.1 × 10⁻⁶) )= - (1947 J mol⁻¹)

Now, substituting the values in the equation,ΔG = ΔG° + RT ln Q= -(1947 J mol⁻¹) + (8.314 J K⁻¹ mol⁻¹ × 298 K × ln (0))= - (1947 J mol⁻¹)The Gibbs free energy change is 1947 J/mol or approximately 1950 J/mol. Therefore, the answer is 1947 J.

mol ?

Express your answer using two significant figures.

Part C

What is the half-life of at 70 degree Celsius?

The answer is the half-life of** N2O5** is approximately** 100 seconds.**

Given that the first-order rate **constant** for the decomposition of N2O5 is 6.82 × 10−3 s−1. The **balanced equation** for the decomposition of N2O5 is 2N2O5(g) → 4NO2(g) + O2(g).a) To calculate the moles of N2O5 remaining after 7.0 minutes, we use the first-order integrated rate law equation: ln ([A]t/[A]0) = −k Where [A]0 and [A]t are the initial and remaining amounts of N2O5 respectively.

Using the above equation, we get: ln ([N2O5]t/[N2O5]0) = −k × t Substituting the values:N2O5]0 = 2.00 × 10−2 mol [N2O5]t = ?k = 6.82 × 10−3 s−1t = 7.0 min = 420 s\We get: ln ([N2O5]t/2.00 × 10−2) = −6.82 × 10−3 × 420[N2O5]t/2.00 × 10−2 = e−6.82×10−3×420[N2O5]t = 0.0127 moles ≈ 1.3 × 10−2 moles

Therefore, the number of** moles** of N2O5 that will remain after 7.0 minutes is approximately 1.3 × 10−2 moles.b) To calculate the time taken for the quantity of N2O5 to drop to 1.6 × 10−2 mol, we use the same equation: ln ([N2O5]t/[N2O5]0) = −k × t[N2O5]0 = 2.00 × 10−2 mol[N2O5]t = 1.6 × 10−2 molk = 6.82 × 10−3 s−1t = ?Substituting the values: ln (1.6 × 10−2/2.00 × 10−2) = −6.82 × 10−3 × t−0.2231 = −6.82 × 10−3 × tt = 32726.7 seconds ≈ 33000 seconds or 550 minutes

Therefore, the time taken for the quantity of N2O5 to drop to 1.6 × 10−2 mol is approximately 550 minutes or 9 hours (approximately).c)

To calculate the half-life of N2O5, we use the formula for a first-order reaction:t1/2 = 0.693/k Substituting the value of k, we get:t1/2 = 0.693/6.82 × 10−3s−1t1/2 = 101.6 seconds ≈ 100 seconds Therefore,

determine the electron geometry (eg) and molecular geometry (mg) of cbr3 .

The electron geometry (EG) and **molecular geometry** (MG) of CBr₃ are tetrahedral. CBr₃ is a molecule with three Br atoms bonded to a central carbon atom. The electron geometry refers to the geometric arrangement of electron pairs in a molecule or ion.

In a compound, the electron geometry will differ from the molecular geometry because the molecular geometry takes into account the positioning of atoms only. The electron geometry of a molecule is determined by the number of **electron pairs** surrounding the central atom in the molecule. These electron pairs will be either bonding or non-bonding pairs (lone pairs).

To determine the electron geometry of a molecule, we use the VSEPR (Valence Shell Electron Pair Repulsion) theory. This theory states that the electron pairs surrounding a central atom in a molecule will be positioned as far apart as possible in order to minimize **repulsion **between them. Molecular geometry refers to the arrangement of atoms in a molecule.

The molecular geometry of a molecule is determined by the number of atoms bonded to the central atom and the number of lone pairs on the central atom. To determine the molecular geometry of a molecule, we use the same VSEPR theory that we use to determine the electron geometry. However, for molecular geometry, we consider only the atoms bonded to the central atom. We don't consider the lone pairs.

The central atom in CBr₃ is carbon. Carbon has four valence electrons. The three Br atoms around the carbon atom will share electrons with the carbon atom to form a single **covalent bond**, so there will be three bonding pairs of electrons between the Br atoms and the C atom. Carbon will also have one lone pair of electrons.

The presence of four electron pairs around the central atom indicates a tetrahedral electron geometry, which is the same as the molecular geometry in this case since there are no lone pairs on the Br atoms. Thus, the electron geometry and molecular geometry of CBr₃ is tetrahedral.

Estimate the oxygen demand for composting mixed garden waste (units of kg of O2 required per kg of dry raw waste). Assume 1,000 dry kg mixed garden waste has a composition of 513 g C, 60 g H, 405 g O, and 22 g N. Assume 25 percent of the nitrogen is lost to NH3(g) during composting. The final C:N ratio is 9.43. The final molecular composition is c11H1404N.

The estimated **oxygen **demand for composting mixed garden waste is approximately 2.38 kg of O2 required per kg of dry raw waste.

To estimate the oxygen demand for composting mixed garden waste, we can use the information provided.

1. Calculate the oxygen required for **carbon oxidation**:

The amount of oxygen required for carbon oxidation can be determined using the stoichiometry of the reaction. Assuming complete oxidation, each gram of carbon requires 2.67 grams of oxygen. Thus, for 513 g of carbon, the oxygen required is 513 g * 2.67 g [tex]O_2[/tex]/g C = 1370.71 g [tex]O_2[/tex].

2. Calculate the oxygen required for hydrogen oxidation:

Similar to carbon, each gram of hydrogen requires 8 grams of oxygen for complete oxidation. For 60 g of hydrogen, the oxygen required is 60 g * 8 g [tex]O_2[/tex]/g H = 480 g [tex]O_2[/tex].

3. Calculate the oxygen required for **nitrogen oxidation**:

Since 25% of the nitrogen is lost as NH3 during composting, only 75% of the initial nitrogen remains. The final molecular composition of c11H1404N indicates 1 nitrogen atom per molecule. Thus, the nitrogen content is 22 g * 0.75 = 16.5 g. This requires 16.5 g * 32 g [tex]O_2[/tex]/g N = 528 g [tex]O_2[/tex].

4. Calculate the total oxygen demand:

Summing up the oxygen required for carbon, hydrogen, and nitrogen oxidation, we have:

[tex]1370.71 g O_2 + 480 g O_2 + 528 g O_2 = 2378.71 g O_2.[/tex]

Finally, to convert this to a ratio, divide the oxygen demand by the dry weight of the mixed **garden waste**. Assuming 1000 kg of dry mixed garden waste, the oxygen demand is 2378.71 g [tex]O_2[/tex] / 1000 kg = 2.38 kg [tex]O_2[/tex] per kg of dry raw waste.

Therefore, the estimated oxygen demand for composting mixed garden waste is approximately 2.38 kg of [tex]O_2[/tex] required per kg of dry raw waste.
