Which of the following statements is true regarding a catalyst in a reversible chemical reaction at equilibrium?
A. It alters the equilibrium constant of the reaction significantly.
B. It increases the yield of the forward product at equilibrium.
C. It speeds up the forward and reverse reactions equally without changing the equilibrium composition.✓ Correct Answer
D. It is consumed permanently during the reaction cycles.
💡 Solution & Explanation
A chemical catalyst functions by providing an alternate reaction pathway with a lower activation energy, accelerating both the forward and reverse reactions by the exact same proportion, thereby achieving chemical equilibrium faster without altering the equilibrium constant or composition. It is regenerated at the end of the reaction cycle and does not affect the final yield of products. Catalytic efficiency is a core principle studied in physical chemistry for industrial chemical synthesis.
