Webwhere n is the reaction order. From this equation, a general formula for the units of k is obtained which is: k units = M 1-n · t-1. where n is the reaction order. For example, let’s say we want to determine the units of the rate constant for third-order reactions. n = 3, and therefore, k units = M 1-3 · t-1 = M-2 · t-1
