Question

Which one of the following statements is not correct?

Options

• Catalyst does not initiate any reaction.

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

• Enzymes catalyse mainly biochemical reactions.

• Coenzymes increase the catalytic activity of enzymes.

Answer 1

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

Explanation:

This statement is not correct because a catalyst does not change the equilibrium constant; it only speeds up the rate at which equilibrium is reached without altering the position or value of the equilibrium constant.
