Question

if the activation energy required for a chemical reaction were reduced, what would happen to the rate of the reaction?
the rate would increase.
the rate would decrease.
the rate would remain the same.
the rate would be zero.

Explanation:

Activation energy is the minimum energy reactant molecules need to undergo a reaction. A lower activation energy means more reactant molecules can reach the energy threshold to react in a given time. So, reducing activation energy increases the number of effective collisions, thus increasing the reaction rate.

Answer:

A. The rate would increase.
