Understand that the rate law expresses the rate of a chemical reaction in terms of the concentration of reactants and a rate constant. The general form is Rate = k[A]^m[B]^n[C]^p, where m, n, and p are the orders with respect to each reactant.
Identify the given rate law: Rate = k[A][B][C]. This implies that the concentration of each reactant is raised to the power of 1.
Determine the order of the reaction with respect to each reactant. In this case, [A] is raised to the power of 1, [B] is raised to the power of 1, and [C] is raised to the power of 1.
Calculate the overall reaction order by summing the individual orders of the reactants. Add the exponents: 1 (for [A]) + 1 (for [B]) + 1 (for [C]).
Conclude that the overall reaction order is the sum of the individual orders, which is 3.
