An enzyme affects the rate of a chemical reaction by
A) decreasing the free energy of the reaction.
B) increasing the free energy of the reaction.
C) lowering the energy of activation of the reaction.
D) raising the energy of activation of the reaction.
E) displacing the equilibrium constant.

Question

Quizplus · Accepted Answer

Enzymes lower the energy of activation of a reaction, which increases the rate of the reaction. This is achieved by stabilizing the transition state of the reaction, making it easier for molecules to undergo the reaction.
