What is Rate Law?
A mathematical expression relating the rate of a chemical reaction to the concentrations of reactants raised to experimentally determined powers: Rate = k[A]ᵐ[B]ⁿ. The exponents (m, n) are the reaction orders, determined experimentally, not from the balanced equation (unless elementary).
