The enthalpy change for the conversion of

\frac{1}{2} \mathrm{Cl}_{2}(\mathrm{~g})

\mathrm{Cl}^{-}

(aq) is (

-

) ___________

\mathrm{kJ} \mathrm{mol}^{-1}

(Nearest integer) Given :

\Delta_{\mathrm{dis}} \mathrm{H}_{\mathrm{Cl}_{2(\mathrm{~g})}^{\theta}}^{\ominus}=240 \mathrm{~kJ} \mathrm{~mol}^{-1}, \Delta_{\mathrm{eg}} \mathrm{H}_{\mathrm{Cl_{(g)}}}^{\ominus}=-350 \mathrm{~kJ} \mathrm{~mol}^{-1}

{\mathrm{\Delta _{hyd}}H_{Cl_{(g)}^ - }^\Theta = - 380}

\mathrm{kJ~mol^{-1}}
