The enthalpy change for the conversion of$\frac{1}{2}{\mathrm{Cl}}_2$(g) to${\mathrm{Cl}}^{-}\left(\mathrm{aq}\right)$is$(-)$
${\mathrm{kJmol}}^{-1}$(Nearest integer)
Given :${\Delta }_{\text{dis }}{\mathrm{H}}_{{\mathrm{Cl}}_{2( \mathrm{g})}}^0=240{\mathrm{kJmol}}^{-1}$.
${\Delta }_{\mathrm{eg}}{\mathrm{H}}_{\mathrm{Cl}\left(\mathrm{g}\right)}^{\mathrm{o}}=-350{\mathrm{kJmol}}^{-1}$,
${\Delta }_{\mathrm{hyd}}{\mathrm{H}}_{{\mathrm{Cl}}_{\left(\mathrm{g}\right)}^{-}}^{\mathrm{o}}=-380{\mathrm{kJmol}}^{-1}$
