Which one of the following statements is not correct?

Which one of the following statements is not correct?

Options

  1. ACatalyst does not initiate any reaction.
  2. BThe value of equilibrium constant is changed in the presence of a catalyst in the reaction at equilibrium.
  3. CEnzymes catalyse mainly bio-chemical reactions.
  4. DCoenzymes increase the catalytic activity of enzyme.

Correct answer

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

Step-by-step solution

A catalyst decreases activation energies of both the forward and backward reaction by same amount, therefore, it speeds up both forward and backward reaction by same rate.

Equilibrium constant is therefore not affected by catalyst at a given temperature.
