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 Reaction Rate Law π Based on the reaction mechanism, we can now derive a rate law. π The rate law of a reaction expresses the speed of the reaction in terms of the concentrations of reactants and/or intermediates or catalysts and the rate coefficients of the elementary reactions. π The overall rate law is given by: rate = K [A]y[B]z WebJan 12, 2024 · In general, the rate law can calculate the rate of reaction from known concentrations for reactants and derive an equation that expresses a reactant as a function of time.
