Warren May 29, 2016, 06:30:11 PM #1 Answer The simplest sequential reaction involves two elementary reaction steps in which the reactant decays to form an intermediate species in the first step, then the intermediate proceeds to form product in the second step. An intermediate is a chemical species that is both produced during the course of the reaction, and subsequently decays resulting in product formation. Sarah May 29, 2016, 06:45:50 PM #2 Keep it up!
