First-Order ECrev Mechanism Including a Third Species

First-Order ECrev Mechanism Including a Third Species 

the first-order ECrev mechanism will be discussed as an example of electrochemical problems with a coupled equation system and more than two species. The reaction scheme corresponding to the ECrev mechanism can be written as 

After the normalisation and discretisation of the problem, the equations corresponding to a point i in solution of the linear system to solve are given by 

For the points situated at the electrode surface (i = 0) and bulk solution (i = n — 1), the boundary conditions discussed in the previous sections of this chapter apply. The resulting problem can be solved with the algorithm for banded linear equation systems given in Section 5.3.
