WebThe Nernst equation should give us that the cell potential is equal to the standard cell potential. Let's find the cell potential again for our zinc copper cell but this time the concentration of zinc two plus ions is 10 molar, and we keep the concentration of copper two plus ions the same, one molar. So if we're trying to find the cell ... 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.
