What is the standard free energy change for the cell, having following cell reaction? $2 \mathrm{Ag}_{(\mathrm{aq} .)}^{+}+\mathrm{Cd}_{(\mathrm{s})} \longrightarrow 2 \mathrm{Ag}_{(\mathrm{s})}+\mathrm{Cd}_{(\mathrm{aq})}^{2+}, \mathrm{E}^{\circ} \mathrm{cell}=1 \cdot 20 \mathrm{~V}$

The correct answer is:
$-231 \cdot 6 \mathrm{~kJ}$
$2 \mathrm{Ag}_{(\mathrm{aq})}^{+}+\mathrm{Cd}_{(\mathrm{s})} \longrightarrow 2 \mathrm{Ag}_{(\mathrm{s})}+\mathrm{Cd}_{(\mathrm{aq})}^{2+}$
$\therefore \mathrm{n}=2$
$\Delta \mathrm{G}^{0}=-\mathrm{nFE}_{\mathrm{cell}}^{0}=-2 \times 96500 \times 1.20=-231600 \mathrm{~J}=-231.6 \mathrm{~kJ}$
$\therefore \mathrm{n}=2$
$\Delta \mathrm{G}^{0}=-\mathrm{nFE}_{\mathrm{cell}}^{0}=-2 \times 96500 \times 1.20=-231600 \mathrm{~J}=-231.6 \mathrm{~kJ}$
