Which of the following correctly describes the effect of a catalyst on a chemical reaction? Select all that apply.
A) It increases the rate of the forward reaction.
B) Catalysts decrease the rate of the back reaction.
C) Catalysts lower the activation energy of a reaction.
D) Catalysts decrease the time required for equilibrium to be established.
E) Catalysts never allow equilibrium to be reached

Question

Quizplus · Accepted Answer

A catalyst increases the rate of both the forward and reverse reactions by lowering the activation energy, thus decreasing the time required to reach equilibrium. It does not prevent equilibrium from being reached.
