42 energy diagram for two step reaction
The energy diagram of a two-step reaction is shown below. In the above reaction, a reactant goes through one elementary step with a lower activation energy (transition state 1) to form the intermediate. The intermediate then goes through a second step (transition state 2) with the highest energy barrier to form the product. Draw an energy diagram for a two-step reaction that is exothermic overall, and consists of a fast but endothermic first step, and a slow but exothermic second step. Indicate DG rxn, as well as DG 1 * and DG 2 * for the first and second activation energies, respectively. Label the positions corresponding to the transition states with an asterisk.
