The reaction is exothermic. The reaction is slow at 25˚C; however, a catalyst will cause the reaction to proceed faster. (e) Using the axes provided, draw the complete potential-energy diagram for both the catalyzed and uncatalyzed reactions. Clearly label the curve that represents the catalyzed reaction.
