Kinetic analysis Temkin equation

This uncertainty makes the kinetic analysis in terms of Frumkin and Temkin adsorption isotherms also uncertain. As long as there is no clear evidence to the contrary, it may be safer to rely on a simple form of a kinetic equation consistent with the Langmuir adsorption isotherm. Therefore, it is usually accepted that in not too concentrated acids the OER occurs on Pt according to... 

The use of cyclic graphs proved to be very fruitful for the deduction of kinetic equations and in the analysis of kinetic data for linear mechanisms. It should also be mentioned that Temkin s kinetic graphs provide a unique approach to both catalytic and non-catalytic reactions. In the latter case, one of the graph vertices contains a zero intermediate of concentration 1 not included in the kinetic equations. Thus, the use of kinetic graphs for non-catalytic reactions is justified only for mechanisms with at least one intermediate.
