Ag^+( aq )+ e^- → Ag ( s ) E^°=+0.80 V Fe^2+( aq )+2 e^- → Fe ( s ) E^°=-0.44 V Find the E_cell^° for: Fe ( s )+2 Ag^+( aq ) → Fe^2+( aq )+2 Ag ( s )

$\displaystyle \mathrm{Ag}^{+}(\mathrm{aq})+\mathrm{e}^{-} \longrightarrow \mathrm{Ag}(\mathrm{s}) \quad \mathrm{E}^{\circ}=+0.80 \mathrm{~V}$ $\displaystyle \mathrm{Fe}^{2+}(\mathrm{aq})+2 \mathrm{e}^{-} \longrightarrow \mathrm{Fe}(\mathrm{s}) \quad \mathrm{E}^{\circ}=-0.44 \mathrm{~V}$ Find the $\displaystyle \mathrm{E}_{\text {cell }}^{\circ}$ for: $\displaystyle \mathrm{Fe}(\mathrm{s})+2 \mathrm{Ag}^{+}(\mathrm{aq}) \longrightarrow \mathrm{Fe}^{2+}(\mathrm{aq})+2 \mathrm{Ag}(\mathrm{s})$
