WebMar 13, 2024 · For a endothermic reaction, the products will have a higher overall energy than the reactants. Since the profile is the same, the products staring at a higher energy will mean that less energy is needed to be put in to reach the transition state. Thus, the activation energy will be less for the reverse reaction of an endothermic reaction. WebThe energy profile for a multistep reaction can be used to compare the activation energies of the different steps and identify the rate-determining step. The energy profile can also …
