Deriving a rate law from a reaction mechanism

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 SN2 mechanism is a concerted mechanism because the nucleophile attacks the electrophile, at the same time we get loss of a leaving groups. There's only one step in this mechanism. Let's say we did a series of experiments to determine the rate law for this reaction. Remember from general chemistry, rate laws are determined experimentally.

WebIn general, when the rate-determining (slower) step is the first step in a mechanism, the rate law for the overall reaction is the same as the rate law for this step. However, when the rate-determining step is preceded by a step involving an equilibrium reaction, the rate law for the overall reaction may be more difficult to derive.
