The document discusses determining reaction orders from rate laws and experimental data. It provides examples of using rate law data to calculate the individual reaction orders with respect to each reactant and the overall order. The key points are: - Reaction orders are determined by the exponents in the rate law, not the coefficients in the balanced chemical equation. - To determine the order with respect to a reactant, experiments are run where its concentration is varied while others are held constant. - Orders can be found by taking the ratio of rates and solving equations relating rate changes to concentration changes. - Reaction orders can be positive integers, zero, negative integers, or fractions.
