The following phase diagram shows how a catalyst affected the rate of a reaction.

which statement below best describes how the catalyst affected the reaction shown in this diagram?

a. the catalyst decreased the activation energy of the reactants.
b. the catalyst increased the activation energy of the reactants.
c. the catalyst increased activation energy of the products.
d. the catalyst decreased activation energy of the products.

The correct answer is "The catalyst decreased the activation energy of the reactants."

Explanation:

Activation energy is the minimum energy required to start a reaction. A catalyst lowers the activation energy of a reaction. Here the catalyst lowers the activation energy of the reactant, thus making it easier to start to the reaction. In the absence of a catalyst the activation energy of the reactant will be higher.

the answer to your question is c.
