Coupled homogeneous electrode reactions catalytic reaction

Fig. 13. Diagnostic plots for electrode reactions with coupled homogeneous reactions, illustrated for the RDE. (a) CE mechanism. Curve A, no effect from chemical reaction (5k = 0) curve B, effect of preceding chemical reaction (5k >0). (b) Catalytic mechanism. Curve A, in the absence of parallel chemical reaction curve B, experimental dependence predicted from eqn. (175).

As discussed in previous chapters (see Sects. 3.4.1, 4.5.1 and 6.3.1), of the processes with first- or pseudo-first-order homogeneous reactions coupled to the charge transfer, the catalytic mechanism is the simplest to study. The solution corresponding to SWV corresponding to planar, spherical, and disc electrodes will be discussed.
