Pick the correct statement.

Pick the correct statement.
  1. Relative lowering of vapour pressure is independent of $\mathrm{T}$.
  2. Osmotic pressure always depends on the nature of solute.
  3. Elevation of boiling point depends on of nature of the solute.
  4. Lowering of freezing point is proportional to the molar concentration of solute.

Solution

Relative lowering of vapour pressure is $\frac{\Delta \mathrm{P}}{\mathrm{P}^{\circ}}$, which is equal to mole fraction of solute which is independent of temperature. /
