Draw an energy diagram for a fictitious, exergonic, three-step reaction where the third step is the rate-determining step. Label your axes, the intermediates, the transition states and the H for the reaction. TS 1 TS 2 TS 3 R I 1 I 2 P E Reaction Coordinate ! H 2. Use the following energy diagram to answer the questions below: E Reaction Coordinate ! H rxn ! H 1 ! H 2 ! H 3 ! H 4 a) How many steps are in the mechanism to this reaction? There are 4 steps to this mechanism. b) Which step is the rate-determining step? The second step, with the highest activation barrier, is the RDS. c) Label H rxn and the activation energies on the graph. Chemistry 211 Clark College Exam 2 Review Fall 2007 Page 2 of 4 3.
