HW 10 Chapter 10 Kinetics Rx rate (positive) = + [product]/ (product coefficient) time = – [reactant]/ (reactant coefficient) time notation: [] = concentration in mol/L Rate Law Rate = k[X] m [Y] n exponents: “ order with respect to” measured experimentally Determination of Rate Law (exponents = 0, 1, or 2) Differential: reaction rates as function of reactant concentration Integrated: reactant concentration as a function of time First order kinetics: half life
