Answer: Reducing the activation energy can increase the rate of a reaction.

Explanation: The rate of a chemical reaction can be defined as the rate of the formation of products or the rate of disappearance of reactants. Activation energy of a reaction is an energy barrier that must be overcome before the reaction can occur. It is the minimum amount of energy that can be possessed by the reactants before products can be formed. Lowering the activation energy of a reaction will therefore increase the rate of the reaction because the reactants will possess enough energy to easily overcome the barrier.
