Abstract:
The energetic span model allows the estimation of the turnover frequency (TOF) of a catalytic reaction from its calculated energy profile. Furthermore, by identifying the TOF determining intermediate and the TOF determining transition state, the model shows that the concept of "determining states" is more useful and correct than the concept of "determining steps." This article illustrates the application of the model and provides an introduction to its concepts using instructive examples. The first part explains the model in its current state of development, whereas in the second part the degree of TOF control of the reactant and product concentrations is introduced. With this information, it is possible to give explicit recommendations regarding the conditions to be applied in the experiment, e.g., which reactant promotes the reaction or if a product kinetically inhibits it. At the end, we present the AUTOF program that allows the user to apply the complete model in a black box fashion.
