Calculate $\Delta \mathrm{G}^{\circ}$ for the cell: $\mathrm{Sn}_{(\mathrm{s})}\left|\operatorname{Sn}_{(\mathrm{IM})}^{++}\right|\left|\operatorname{Ag}_{(\mathrm{IM})}^{+}\right| \mathrm{Ag}_{(\mathrm{s})} \text { at } 25^{\circ} \mathrm{C}\left(\mathrm{E}_{\text {cell }}^{\circ}=0.90 \mathrm{~V}\right)$
  1. $-173.7 \mathrm{~kJ}$
  2. $-225.3 \mathrm{~kJ}$
  3. $-100.2 \mathrm{~kJ}$
  4. $-290.8 \mathrm{~kJ}$

Solution

$\begin{aligned} \Delta \mathrm{G}^{\circ} & =-\mathrm{nF}_{\text {cell }}^{\circ} \\ & =-2 \times 96500 \times 0.90 \\ & =-173700 \mathrm{~J} \\ & =-173.7 \mathrm{~kJ}\end{aligned}$
