Abstract
The dc polarographic response for the parallel ECE mechanism with Nernstian behavior is examined. Explicit equations for the current-potential curves which take into account effects of electrode sphericity, chemical reaction reversibility and influences of the rate constants of the chemical reaction, have been derived rigorously without using the steady-state approximation. If K, k 1 and k 2 are, respectively, the equilibrium constant and the rate constants of the chemical reaction, it is shown that we can determine these parameters when the current-potential curves show two waves.
