44 multi step reaction energy diagram

Does the rate determining step have the highest activation energy ... Answer: Not necessarily. In a multi-step mechanism, the reaction coordinate diagram has a lot of peaks and valleys, but the rate determining step is the last one that brings you to the top of the mountain. Often the activation energy for this step is much smaller than the one(s) that precede it. ... Reaction Profiles; Rate Limiting Steps – Chem 103/104 Resource ...
