The voltage of a cell whose half cell reactions are given below is

${\mathrm{Mg}}^{2+}+2{\mathrm{e}}^{-}⟶\mathrm{Mg}\left(\mathrm{s}\right); \mathrm{E}=-2.37 \mathrm{V}$

${\mathrm{Cu}}^{2+}+2{\mathrm{e}}^{-}⟶\mathrm{Cu}\left(\mathrm{s}\right); \mathrm{E}=+0.34 \mathrm{V}$

The hydrogen electrode is dipped in a solution of $\mathrm{pH}=3$ at $25° \mathrm{C}$. The reduction potential of the electrode would be:

$\mathrm{Zn}\left|{\mathrm{Zn}}_{\left(\mathrm{ag}\right)}^{2+}\Vert {\mathrm{Cu}}_{\left(\mathrm{ag}\right)}^{2+}\right|\mathrm{CuE}°$ for the cell is $1.10 \mathrm{V}$ at $25° \mathrm{C}$. The equilibrium constant for the cell reaction is of the order of
