WebDec 28, 2024 · In one version of the Arrhenius equation, you can calculate the rate of a first-order chemical reaction. First-order chemical reactions are ones in which the rate of reactions depends only on the concentration of one reactant. The equation is: 00:00 00:00 An unknown error has occurred Brought to you by Sciencing K=Ae^ {-E_a/RT} K = Ae−Ea/RT WebOne way is to use the method of initial rates. A rate law shows how a change in concentration affects the rate. The equation for a component A is rate = k[A]m, where m is the order of the reaction. Zero Order rate = k[A]0 = k The rate does not depend on the concentration. Whatever you do to the concentration, the rate will not change. First Order
