Question

All of the following may be true concerning catalysts and the reaction which catalyse except,

• A. catalysts are not used up by the reaction
• B. catalysts lower the energy of activation
• C. catalysts increase the rate of the reverse reaction
• D. catalysts shift the reaction equilibrium to the right

Hint:

Remember, catalysts affect the rate of the reaction but not the equilibrium.

Answer 1

The Correct Option is D

Catalysts speed up the reaction by lowering the activation energy, but they do not shift the position of the equilibrium. Catalysts provide an alternative pathway for the reaction, but they do not change the equilibrium constant. Thus, the correct answer is (d) catalysts shift the reaction equilibrium to the right.
