We know${\text{ΔG}}^{\text{o}}=-\text{nFE}°$
Again according to Nernst equation,
$\mathrm{E}°=\frac{0.059}{\mathrm{n}}\mathrm{l}\mathrm{o}\mathrm{g}\frac{\left[\mathrm{Z}{\mathrm{n}}^{2+}\right]}{\left[\mathrm{C}{\mathrm{u}}^{2+}\right]}$, at 25°C
So${\text{ΔG}}^{\text{o}}$(free energy change) in an electrochemical cell at a given temperature is a function of
$\mathrm{l}\mathrm{n}\frac{\left[\mathrm{Z}{\mathrm{n}}^{2+}\right]}{\left[\mathrm{C}{\mathrm{u}}^{2+}\right]}=\mathrm{l}\mathrm{n}\left(\frac{{\mathrm{C}}_2}{{\mathrm{C}}_1}\right)$
