Tempkin

The rate-determining step is the surface combination of C0ads with OH to give a carboxylic group. The remarkable slope of 120 mv, so easily confused with a discharge mechanism, can be interpreted if these adsorptions are Tempkin in type, in terms of the mechanism equations 12-15, if the 9 dependence is relatively small (equation 16).

Several different mathematical relationships (referred to as isotherms) have been developed to describe the relationship of fractional surface coverage with respect to the adsorbing species. Work by Langmuir, Freundlich, Tempkin, and others have attempted to describe the above mentioned pressure differential to fractional surface coverage. The most widely used and accepted isotherm is the BET equation, named after its orignators, Brunauer, Emmett, and Teller, and is as follows 29...
