THERMODYNAMICAL PROPERTIES OF ROTATING DISK ELECTRODES FOR SECOND ORDER ECE REACTIONS

ABSTRACT
The thermodynamical model for rotating disk electrodes for second order ECE (electrochemical-chemical-electrochemical) reactions is considered, and the effect of concentrations of three species on the current for ECE reaction is theoretically analyzed, and the optimal current value is obtained. The Taylor series method is used, the derivation is simple and the accuracy can be improved if higher order Taylor series is considered. A fractal modification is also suggested for future research.
