The cell reaction for following galvanic cell is  $Pt.C{l}_{2\left(g\right)}C{l}^{-}\left(1M\right)F^{-}\left(1M\right)/F_{2\left(g\right)},Pt$

$F_{\left(aq\right)}^{-}+C{l}_{\left(g\right)}^{-}\rightleftharpoons \frac{1}{2}{F}_{2\left(g\right)}+\frac{1}{2}C{l}_{2\left(g\right)}$

$F_{\left(aq\right)}^{-}+\frac{1}{2}C{l}_{2\left(g\right)}\rightleftharpoons C{l}_{\left(aq\right)}^{-}+\frac{1}{2}{F}_{2\left(g\right)}$

$\frac{1}{2}{F}_{2\left(g\right)}+\frac{1}{2}C{l}_{2\left(g\right)}\rightleftharpoons F_{\left(g\right)}^{-}+C{l}_{\left(g\right)}^{-}$

$C{l}_{\left(aq\right)}^{-}+\frac{1}{2}{F}_{2\left(g\right)}\rightleftharpoons \frac{1}{2}C{l}_{2\left(g\right)}+F_{\left(aq\right)}^{-}$
