What happens when you increase the temperature of a reaction? a. more collisions occur and the time required for the reaction increases b. fewer collisions occur and the time required for the reaction decreases c. fewer collisions occur and the time required for the reaction increases d. more collisions occur and the time required for the reaction decreases.

Option (D) is the correct answer.

more collisions occur and the time required for the reaction decreases.

Explanation:

When we increase the temperature of reactant molecules then there will occur an increase in the kinetic energy of molecules.

Also,      K.E =

So, kinetic energy is directly proportional to the temperature. As a result, more number of collisions will take place between the molecules due to which there will be an increase in the rate of reaction.

Therefore, we can conclude that when you increase the temperature of a reaction then more collisions occur and the time required for the reaction decreases.
