Deriving nernst equation
In electrochemistry, the Nernst equation is a chemical thermodynamical relationship that permits the calculation of the reduction potential of a reaction (half-cell or full cell reaction) from the standard electrode potential, absolute temperature, the number of electrons involved in the redox reaction, and activities (often approximated by concentrations) of the chemical species undergoing reduction and oxidation respectively. It was named after Walther Nernst, a German physical chemist who for… Web1.3.1 Nernst equation. The Nernst equation solves the potential of an electrochemical cell containing a reversible system with fast kinetics and it is valid only at equilibrium and at the surface of the electrode: where E0′ [V] is the formal potential, E0 [V] is the standard potential, C* [mol L −1] is the bulk concentration for the ...
