Quantity defined by \(E^{\unicode{x26ac}} = -\frac{\Delta _{\text{r}}G^{\,\unicode{x26ac}}}{n\ F}=\frac{R\ T}{n\ F}\ \ln K^{\,\unicode{x26ac}}\), where \(\Delta _{\text{r}}G^{\,\unicode{x26ac}}\) is the standard Gibbs energy of the cell reaction in the direction in which reduction occurs at the right-hand electrode in the diagram representing the cell ('reduction at right'), \(K^{\unicode{x26ac}}\) is the standard @E02177@ for this reaction, \(n\) its @C00993@, \(F\) the @F02325@, \(R\) the @G02579@ and \(T\) the @T06321@.
