Theoretical overpotential
Did you know?
WebbIn battery, overpotential is the potential difference (or voltage measure) between a theoretical or thermodynamically determined voltage and the actual voltage under operating conditions. To understand this clearly, let … In electrochemistry, overpotential is the potential difference (voltage) between a half-reaction's thermodynamically-determined reduction potential and the potential at which the redox event is experimentally observed. The term is directly related to a cell's voltage efficiency. In an electrolytic cell the existence of … Visa mer The four possible polarities of overpotentials are listed below. • An electrolytic cell's anode is more positive, using more energy than thermodynamics require. • An electrolytic cell's Visa mer Overpotential can be divided into many different subcategories that are not all well defined. For example, "polarization overpotential" can refer to the electrode polarization and the Visa mer • Electrolysis • Electrosynthesis Visa mer
