Consider a reaction in which E_a = 73 kJ and ΔH = –8 kJ. In the presence of a catalyst, the activation energy is 59% of the activation energy for the uncatalyzed reaction. Follow the directions in Question 71 in drawing an energy diagram.

Reference Question 71:

For a certain reaction, E_a is 135 kJ and ΔH = 45 kJ. In the presence of a catalyst, the activation energy is 39% of that for the uncatalyzed reaction. Draw a diagram similar to Figure 11.11 but instead of showing two activated complexes (two humps) show only one activated complex (i.e., only one hump) for the reaction. What is the activation energy of the uncatalyzed reverse reaction?
