Draw this mechanism again and in each of the two steps label both the nucleophile and the electrophile (so, that's four labels). Problem EA1.2. Draw a reaction progress diagram for the reaction of 2-methylpropene with hydrogen bromide. The reaction whose potential energy diagram is shown in the figure is a two-step reaction. The activation energy for each step is labeled E a1 and E a2 .Each elementary step has its own activated complex, labeled AC 1 and AC 2 .Note that the overall enthalpy change of the reaction is unaffected by the individual steps, since it depends only on the initial and final states. A Two-Step Reaction Mechanism. The transition states are located at energy maxima. The reactive intermediate B+ is located at an energy minimum. Each step has its own delta H and activation energy. The overall energy difference between the starting materials and products is delta H overall. Step 1 has the higher transition energy state, thus it is the rate-determining step. Consider the one-step conversion of F to G. Given that the reaction is endothermic by 5 kcal/mol and that the energy difference between G and the transition state for the process is 15 kcal/mol, sketch a reaction-energy diagram for this reaction. Make sure to show how the given energy differences are consistent with your sketch.

Label the positions corresponding to the transition states with an asterisk. ? is the complex created in the first reaction, while is the activated complex created in the second reaction. Thus, for this two-step process, there are two activated complexes. Example: Draw the potential energy diagram for the following multi-step reaction . Properly label the diagram. Solution: Rate of Reaction is Determined by Slowest Step Draw and label potential energy diagram for the reaction including a molecular structure that could represent an activated complex.
