The rate law is an equation that relates the reaction rate to the concentrations of reactants and the specific rate constant. It can be determined experimentally by measuring the reaction rate at different concentrations of reactants. The general form of the rate law is: Rate = k [A]^m [B]^n where k is the rate constant, [A] and [B] are the concentrations of reactants, and m and n are the reaction orders with respect to each reactant. By analyzing the experimental data, one can determine the values of k, m, and n.
