12. A flux approximation involving more than two points will lead to inaccuracies at high rate constants due to the singularity that develops in the concentration distribution of the C species adjacent to the electrode surface (see ref 6). This singularity may be overcome with finer meshing; however, this significantly increases computational demands.
