In many instances the rate data are correlated before a mechanism is found. It is a normal procedure to reduce the additive constant in the denominator to 1. We therefore divide the numerator and denominator of Equation (9-9) by k3 to obtain
The rules of thumb listed in Table 9-2 may be of some help in the development of a mechanism that is consistent with the experimental rate law.
