Question : 71 of 80

Marks: +1, -0

Relative lowering of vapour pressure is independent of $T$ .
Osmotic pressure always depends on the nature of solute.
Elevation of boiling point is independent of nature of the solvent.
Lowering of freezing point is proportional to the molar concentration of solute.

Solution:

Hint:

Relative lowering of vapour pressure is

\; \frac{\Delta P}{P^{\circ}}

, which is equal to mole fraction of solute which is independent of temperature.
