Does molecularity include intermediates

WebAboutTranscript. An elementary reaction is a reaction that occurs in a single step. The rate law for an elementary reaction can be derived from the coefficients of the reactants in the balanced equation. For example, the rate law for the elementary reaction 2A + B → products is rate = k[A]² [B]. Created by Jay. WebThe following reaction occurs in a two-step mechanism: Determine the overall reaction equation. Write the rate law for the overall reaction. Solution. Add the two elementary steps together and cancel out any intermediates to give …
