E cell = E 0 – [RT/nF] ln Q. Where, The calculation of single electrode reduction potential (E red) from the standard single electrode reduction potential (E° red) for an atom/ion is given by the …

Calculate the number of moles of electrons transferred in the balanced equation, n. Substitute values into the Nernst equation and solve for the non-standard cell potential, E cell.

To find n, the most effective approach is to write the half-reactions for oxidation and reduction and subsequently balance the equations to ensure an equal number of electrons in both. The …
