Significance of rate law
WebMay 10, 2024 · The rate law is expressed rate = k [A] m [B] n [C] o, where k is the rate constant. A, B, and C are reactant concentrations, and m, n, and o are the partial reaction orders for each reactant. WebThe instantaneous rate is the change in the reactant or product at any given time and is determined by examining the slope of the curve in the plot of concentration vs time. As an example, reactant A's, instantaneous rate is represented as rate = -dA/dt. The rate law for a reaction is measured experimentally.
