ECE and related mechanisms

The ECE and DISP mechanisms, which describe overall two-electron processes, are expressed by 

First consider the theory for an ECE process. In terms of the normalized variables %, and K where 

The boundary conditions appropriate to the problem when the electrode potential is such that the flux of A to the electrode is diffusion-limited, and all C arriving there is destroyed, are defined in Table 4. 

We will show below how this problem is solved when the Singh and Dutt
