Chem111 Fall, 2005 kinetics-9We ended the last lecture with a tool for using experiments to determine kinetic rate laws … now the details of how to do this! •the initial rate method uses differential rate laws •the graphical method uses the integrated rate laws Initial Rate Method Basic steps1. measure the initial rate of a reaction under several different initial concentration conditions 2. compare the initial rates measured to dissect out Æthe orders with respect to each of the reactants Æthe overall order of the reaction Æthe rate constant k for the reaction Initial rate.
