Problem

For the cell

\text{Mg(s)} | \text{Mg}^{2+}(\text{aq.}) || \text{Ag}^+(\text{aq.}) | \text{Ag(s)}

, calculate the equilibrium constant at

25^\circ\text{C}

and the maximum work that can be obtained during operation of cell. Given,

E^\circ_{\text{Mg}/\text{Mg}^{2+}} = +2.37\text{V} \quad \text{and} \quad E^\circ_{\text{Ag}^+/\text{Ag}} = +0.80\text{V},

R = 8.314\text{ J}
