(a) The value of equilibrium constant is changed in the presence of a catalyst in the reaction at equilibrium.

(b) Enzymes catalyse mainly bio-chemical reactions.

(c) Coenzymes increase the catalytic activity of enzyme.

(d) Catalyst does not initiate any reaction.

Answer 1

Ans : (a) The value of equilibrium constant is not change in the presence of a a catalyst in the reaction at equilibrium.

Explanation :

The value of equilibrium constant is not changed in the presence of a catalyst in the reaction at equilibrium. The catalyst increases the rate of forward and reverse reaction to same extent. It does not affect the value of the equilibrium constant.
