What happens as 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.

Explanation:

When we increase temperature of a reaction mixture then reactant molecules gain energy and therefore they move rapidly from one place to another.

As a result, there will be increase in number of collisions between the atoms. Hence, it results in increase of rate of reaction.

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