¹⁰ Strictly speaking, one should compare the product k_AP_C with k_S and k_D.

Dividing r_AD by k_AP_C we note . The reason we do this is that in order to compare terms, the ratios , and must all have the same units . Luckily for us, the end result is the same, however.

¹¹ Some prefer to write the surface reaction rate in terms of the fraction of the surface of sites covered (i.e., f_A) rather than the number of sites C_{A · S} covered, the difference being the multiplication factor of the total site concentration, C_t. In any event, the final form of the rate law is the same because C_t, K_A, k_S, and so on, are all lumped into the reaction rate constant, k.
