Cut to the Chase: Kinetics I. Derive the rate Law A. By definition, the rate law for the reaction : 2 A + 3 B 5 C is: Rate = k [ A ] a [ B ] b Where a and b are called orders of reaction. Note that rate laws are written using the reactants. The orders of reaction, a and b, are not necessarily the coefficients of the equation. In fact, the only time the orders equal the coefficients is when the reactions are elementary reactions (occurring in a single event). B. The orders of the reactions are derives by the following mathematical equation: [ ratios of M of A from two experiments ] a [ rations of B ] b = ratios of the rates If you desire to obtain the order of A, look for two experiments where B remains constant. Then put the concentration of A from experiment one over the concentration of A from experiment two. Raise that to the (a) power. Set that equal to the rate of experiment 1 over the rate of experiment 2. C.
