A catalyst increases the rate of a reaction by providing a different reaction pathway that lowers only the activation energy. raises only the energy of the products. lowers only the energy of the reactants and products. All of these are affected by the presence of a catalyst.

A catalyst increases the overall rate of reaction by lowering the activation energy, Ea, for neither the forward reaction nor the reverse reaction. only the reverse reaction. both the forward reaction and the reverse reaction. only the forward reaction.

Adding a catalyst to a reaction will: - increase the amount of product produced - make the reaction occur faster - lower the energy of the products relative to the reactants - lower the activation energy - provide an alternate pathway for the reaction to occur I, III, and IV I, III, and V I, IV, and V II, III, and IV II, III, and V II, IV, and V
