A method of analysis of polarographic waves of simple electrode processes is proposed. The quasi-reversible half-wave potential, Ec1/2, is involved in the determination of thermodynamic and kinetic parameters of electrode processes. This potential is determined very easily and with great precision. In order to facilitate the use of the method proposed, we have developed a computer program for Windows.
