Single-electrode process, transitional

For many years the Tafel equation was viewed as an empirical equation. A theoretical interpretation was proposed only after Eyring, Polanyi and Horiuti developed the transition-state theory for chemical kinetics, in the early 1930s. Since the Tafel equation is one of the most important fundamental equations of electrode kinetics, we shall derive it first for a single-step process and then extend the treatment for multiple consecutive steps. Before we do that, however, we shall review very briefly the derivation of the equations of the transition-state theory of chemical kinetics. 

The brief description of uracil adlayers on Au(hkl) also demonstrates that the understanding of 2D phase transition processes on defined solid electrodes, such as singleinterfacial processes associated with the adlayer as well as with the substrate surface.
