How can you increase the rate of a reaction? Select all that apply. *
Introduce a catalyst
Increase temperature
Increase the concentration of products
Decrease concentration of reactants
Answer:
- Increase the concentration of the reactants
-increase the temperature
- introduce a catalyst
The rate of reaction is increased by:-
Increase the concentration of the reactantsincrease the temperatureintroduce a catalyst.What is the rate of reaction?The speed at which a chemical reaction occurs is known as the reaction rate or rate of reaction. It is proportional to the rise in product concentration per unit of time and the fall in reactant concentration per unit of time. Reaction times can differ wildly.
A chemical reaction is a procedure that causes one group of chemical substances to change chemically into another.
The rate of a chemical reaction can be increased by Increasing the concentration of the reactant by increasing the temperature and by introducing a catalyst.
Therefore, the rate of reaction can be increased by doing the actions explained above in the answer.

A cyclist turns a corner with a radius of 50m at a speed of 10m/s. What is the cyclist's acceleration?
Answer:
2 m/s^2
Explanation:
a = v^2/r
a = (10m/s)^2 / 50m
a = 2 m/s^2

A cyclist turns a corner with a radius of 50m at a speed of 10m/s. The cyclist's acceleration is 2 m/s².
What is acceleration?The rate at which an item changes its velocity is known as acceleration, a vector quantity. If an object's velocity is changing, it is acceleration. The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g. It is a vector quantity whose strength or magnitude is determined by the norm and whose direction correlates with a plumb bob.
a = v²/r
a = (10m/s)² / 50m
a = 2 m/s²
