aid draw à reaction 7. A particular uncatalyzed single-step reaction at 298 K has an activation energy of so.o kl/mol and a ÎH =-30.0 kJ/mol. a. Draw a reaction energy diagram for the uncatalyzed reaction, labeling the activation energy and A. b. Calculate the activation energy for the reverse reaction (uncatalyzed). When a catalyst is added, the reaction rate increases by a factor of 25. Calculate the activation energy for the catalyzed reaction. c.
