Pick the correct statement.
- A Relative lowering of vapour pressure is independent of \(\mathrm{T}\).
- B Osmotic pressure always depends on the nature of solute.
- C Elevation of boiling point is independent of nature of the solvent.
- D Lowering of freezing point is proportional to the molar concentration of solute.
Answer & Solution
Correct Answer
(A) Relative lowering of vapour pressure is independent of \(\mathrm{T}\).
Step-by-step Solution
Detailed explanation
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.
