Part I - Multiple Choice. Please circle the letter of the BEST answer. The magnitude of K w indicates that water autoionizes only to a small extent. Catalysts change the mechanism of a reaction.
Catalysts lower the activation energy.
Catalysts lower the energy of the products, causing the reaction to be more exothermic. Catalysts affect the rates of chemical reactions. Catalysts do not undergo permanent change during a reaction. O Show that the mechanism is consistent with the experimentally determined rate law. Assume step 1 is a fast equilibrium, and assume step 3 is fast.
