Abstract

The dc polarographic response for a ECE mechanism with Nernsstian behavior is examined. Equations for the current-potential curves have been deduced which are valid for an electrode expanding in accordance with any power law. Thus, the expressions obtained for a stationary plane electrode or a dme are particular cases of this general solution. It is shown that the analysis of the current-potential curves allows the determination of the rate constants of the chemical reaction when all species are in the solution. In turn, the Er1/2,1 (i = 1,2) valúes can be also obtained if the current-potential curves show two waves well defined.
