The Nernst Equation- Derivation, Application, and Limitations
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… Witryna5 wrz 2024 · Importance of Nernst Equation The Nernst Equation allows for cell potential determination under non – standard conditions.
