WebThis is mainly due to their high overvoltage to hydrogen, which enables the determination of heavy metals (zinc, nickel, cobalt, etc.) and other species with high negative half-wave … WebActivation Overpotential . Chapter 2 starts with a discussion on the electric double layer and its effect on activation overpotential. It will be followed by the derivation of the Butler-Volmer equation that describes the relationship between activation overpotential and current density. Finally, the concept of polarization will be explained.
