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 needed for reactant molecules to undergo a chemical reaction. A catalyst reduces activation energy. When activation energy is reduced, more reactant molecules have enough energy to react, so the frequency of effective collisions increases, leading to a higher reaction rate.

Answer:

A. The rate would increase.
