Determine the rate of a reaction that follows the rate law: rate = k[a]m[b]n, where: k = 1 × 10-2[a] = 2 m[b] = 3 mm = 2n = 1

We determine the rate of a reaction from the given rate law by substituting the given concentrations and the order of the substances. We calculate as follows:

rate = k[A]^m[B]^n
rate = (1 x 10^-2) [2]^2 [3]^1
rate = 0.12 M /s

The rate law of a reaction is an expression that is related to the reaction rate. The parameters used are the concentration or the pressure of the reactants in the reaction. An example would be:

A = B + C

The rate law would be:

Rate = k[A]          where k is the reaction rate constant and determined by doing experiments
