Key Concepts

Rate Law

The rate law is an empirical equation that relates the rate of a chemical reaction to the concentrations of its reactants, each raised to a power representing its order. It is determined experimentally and does not necessarily reflect the stoichiometric coefficients of the balanced chemical equation.

Reaction Order

The reaction order is the sum of the individual orders with respect to each reactant in the rate law. It indicates how the rate is affected by changes in the concentration of each reactant and is determined through experimental observation, often by comparing how changes in concentration affect the rate.

Rate Constant

The rate constant is a proportionality constant in the rate law that provides the scale of the reaction rate. Its value, along with its units, depends on the overall reaction order and is a measure of the intrinsic speed of the reaction under specified conditions.

Experimental Determination of Rate Laws

The initial rate method is a common experimental procedure used to determine the rate law of a reaction. By measuring the initial rates of reaction under varying reactant concentrations, the order with respect to each reactant can be deduced, allowing for determination of both the form of the rate law and the rate constant.
