Identify the correct statement
A hypotonic solution is more concentrated with respect to the other solution separated from it by a semi permeable membrane
At the freezing point of a solution containing a non-volatile solute, the vapour pressure of the liquid solvent becomes less than that of the solid solvent
In case of dissociation of solute particles in a solution, the van't Hoff factor is more than unity because the observed molar mass has a lesser value
The molal boiling point elevation constant for a solvent is directly proportional to its enthalpy of vaporisation
