Step-by-step solution

For complex reactions, the overall rate of the reaction is determined by the slowest step, which is known as the rate determining step. Thus, A matches with R. For a zero order reaction, the rate is equal to the rate constant k . The unit of rate is mol L⁻¹ s⁻¹ , which is the same as the unit of the rate of reaction. Thus, B matches with P. The mathematical expression that relates the rate of a reaction to the concentrations of the reactants is defined as the rate law. Thus, C matches with S. For a first order reac
