(Given, $E_{\mathrm{Mg}^{2+} \mid \mathrm{Mg}}^{\circ}=-2.36 \mathrm{~V}$

and $E_{\mathrm{Cl}_2 \mid 2 \mathrm{Cl}^{-}}^{\circ}=+136 \mathrm{~V}$ )

$\mathrm{Mg}\left|\mathrm{Mg}^{2+}(1 \mathrm{M})\right|\left|2 \mathrm{Cl}^{-}(1 \mathrm{M})\right| \mathrm{Cl}_2(1 \mathrm{~atm}), \mathrm{Pt}$

$\mathrm{Mg}\left|\mathrm{Mg}^{2+}(0.01 \mathrm{M})\right|\left|2 \mathrm{Cl}^{-}(1 \mathrm{M})\right| \mathrm{Cl}_2(1 \mathrm{~atm}), \mathrm{Pt}$

$\mathrm{Mg}\left|\mathrm{Mg}^{2+}(1 \mathrm{M})\right|\left|2 \mathrm{Cl}^{\prime}(0.01 \mathrm{M})\right| \mathrm{Cl}_2(1 \mathrm{~atm}), \mathrm{Pt}$

$\mathrm{Mg}^2\left|\mathrm{Mg}^{2+}(0.01 \mathrm{M}) \| 2 \mathrm{Cl}^{-}(0.01 \mathrm{M})\right| \mathrm{Cl}_2(1 \mathrm{~atm}), \mathrm{Pt}$
