✦ Synopsis

The chlorine and oxygen overpotential in dependence on the current density i (A cmm2) and on the temperature in the range of 15-75°C was measured at y-MnOz and /?-PbO, electrodes in concentrated water solutions of sodium chloride and perchlorate. From the measured values the experimental activation energy in dependence on overpotential was calculated and, for the temperature of 25°C. the constants of Tafel's equation (a, b) (a, i, respectively) were evaluated.
