Reason : In the presence of a more volatile liquid solute, only the solute will form the vapours and solvent will not.
$\Delta {U_{BC}} = - 5\,kJ\,mo{l^{ - 1}},{q_{AB}} = 2\,kJ\,mo{l^{ - 1}}$
$\Delta {W_{AB}} = - 5\,kJ\,mo{l^{ - 1}},{W_{CA}} = 3\,kJ\,mo{l^{ - 1}}$
Heat absorbed by the system during process $CA$ is......$kJ\,mo{l^{ - 1}}$
