Question

For the reaction N2+3H2⇌2NH3, the metals Fe and Mo used as catalyst. which of the following is NOT a reason that catalysts have no effect on the equilibrium state?
A. In the presence of a catalyst, the same amounts of reactants and products will be formed as would form in the uncatalyzed reaction.
B. The addition of a catalyst speeds the rate of both the forward and reverse reactions, resulting in no change to the equilibrium.
C. Catalysts reduce the required activation energy and allow a reaction to reach equilibrium more quickly.
D. Catalysts get used up in the formation of the product.

Answer 1

D. Catalysts get used up in the formation of the product.

Catalysts are never used up in a reaction.
