10.3.1 Is the Adsorption of Cumene Rate-Limiting?

To answer this question we shall assume that the adsorption of cumene is indeed rate-limiting, derive the corresponding rate law, and then check to see if it is consistent with experimental observation. By postulating that this (or any other) step is rate-limiting, we are assuming that the reaction rate constant of this step (in this case kA) is small with respect to the specific rates of the other steps (in this case kS and kD).10 The rate of adsorption is

Need to express Cυ and CC · S in terms of PC, PB, and PP

Because we can measure neither Cv or CC · S, we must replace these variables ...
