Question

A catalyst has no effect on _________.

Answer 1

(1) A catalyst does not affect equilibrium.

(2) Catalyst increases the rate of forward and reverse reactions that pass through the same transition state.

(3) Adding a catalyst makes absolutely no difference to the position of equilibrium. For a dynamic equilibrium to be set up, the forward reaction rates and the back reaction must be equal. This does not happen instantly, and for prolonged reactions, it may take years!

(4) A catalyst speeds up the rate at which a reaction reaches dynamic equilibrium.

(5) A catalyst increases both the forward and backward reactions to the same extent in a reversible reaction under equilibrium.

Therefore, a catalyst has no effect on equilibrium constant.
