Consequences of Temkins Model

To get the total, or overall, rate on this surface, equation 8.13 must be integrated and, to facilitate this an auxiliary variable, u, as defined by equation 8.11, will be utilized. Thus 

Thus the rate on a nonuniform surface described in this manner is  

Note the similarities between the rate expression defined by equation 8.34 and that given by equation 8.9 for a uniform surface the numerators are identical and the denominators contain the same terms, although represented in different ways. 

This derivation was based on a two-step reaction sequence or any reaction that can be simplified to such a sequence. Let us examine how the assumptions involved impact upon the behavior of this surface related to adsorption, kinetic, and catalytic processes.
