Vedclass · Answer

(D) For a solution showing negative deviation from Raoult's law,the intermolecular forces between the components are stronger than those in the pure components.This leads to a decrease in the tendency of molecules to escape into the vapour phase,resulting in a lower total vapour pressure: $P_{T} Since the vapour pressure is decreased,the solution requires more heat to reach the atmospheric pressure,which leads to an increase in the boiling point.Therefore,the correct characteristics are decreased vapour pressure and increased boiling point.

$A$ solution of two miscible liquids showing negative deviation from Raoult's law will have :
