Unformatted text preview: Principles of Chemistry II © Vanden Bout Today Kinetics Rate Laws Finding the order of a reaction Integrated Rate Laws What is the concentration as a function of time? Principles of Chemistry II © Vanden Bout The grand overview of all of the kinetics rate aA + bB cC + dD ! [C] c ! t- ! [A] a ! t = = = k[A] x [B] y we are looking only at the rate of the "forward" reaction This depends only on the concentration of the reactants measure in experiment ¡gure out from data Principles of Chemistry II © Vanden Bout for example rate = k[NO 2 ] 2 this reaction is 2nd order in NO 2 Four Factors that affect a reaction rate 1. Concentration of reactants This is the "rate" law. It is found by looking at the data It depends on the "mechanism" 2NO 2 2NO + O 2 Principles of Chemistry II © Vanden Bout Four Factors that affect a reaction rate 2. Temperature This changes the rate constant k k = A e-Ea/RT Arrhenius Law pre-factor barrier temperature The higher the temperature the more molecules that have enough energy to make it over the barrier Principles of Chemistry II...
