greater than the energy of the incident photon
smaller than the energy of the incident photon
same as that of the incident photon
proportional to the intensity of the incident photon

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
