Question

# Which of the following statements is not correct for the catalyst?A. it catalyses the forward and backward reaction to the same extent.B. it alters $\Delta G$ of the reaction.C. it is a substance that does not change the equilibrium constant of a reaction.D. if provides an alternate mechanism by reducing activation energy between reactants and products.

A catalyst increases the rate of reaction by decreasing the activation energy of the reaction. It does not affect the Gibbs free energy $\Delta G$ of the reaction.
