The cell reaction for following galvanic cell is  ${{\text{ Pt.Cl }}_2}_{\left(\mathrm{g}\right)}\mid {\mathrm{Cl}}^{-}\left(1\mathrm{M}\right)\parallel {\mathrm{F}}^{-}\left(1\mathrm{M}\right)/{\mathrm{F}}_{2\left(\mathrm{g}\right)},\mathrm{Pt}$

${\mathrm{Cl}}_{\left(\mathrm{aq}\right)}^{-}+\frac{1}{2}{\mathrm{F}}_{2\left(\mathrm{g}\right)}\rightleftharpoons \frac{1}{2}{\mathrm{Cl}}_{2\left(\mathrm{g}\right)}+{\mathrm{F}}_{\left(\mathrm{aq}\right)}^{-}$

$\frac{1}{2}{\mathrm{F}}_{2\left(\mathrm{g}\right)}+\frac{1}{2}{\mathrm{Cl}}_{2\left(\mathrm{g}\right)}\rightleftharpoons {\mathrm{F}}_{\left(\mathrm{g}\right)}^{-}+{\mathrm{Cl}}_{\left(\mathrm{g}\right)}^{-}$

${\mathrm{F}}_{\left(\mathrm{aq}\right)}^{-}+\frac{1}{2}{\mathrm{Cl}}_{2\left(\mathrm{g}\right)}\rightleftharpoons {\mathrm{Cl}}_{\left(\mathrm{aq}\right)}^{-}+\frac{1}{2}{\mathrm{F}}_{2\left(\mathrm{g}\right)}$
