In the graph plotted between vapour pressure (V.P.) and temperature (T),

A

PQ is the curve for solvent , XY is the curve of solution and `DeltaT` is depression in freezing point

B

PQ is the curve for solution. XY is the curve for solvent and `DeltaT` is elevation is boiling point

C

PQ is the curve for solvent, XY is the curve for solution and `DeltaT` is molal elevation in boiling point

D

PQ is the curve for solvent, XY is the curve for solution and `DeltaT` is elevation in boiling point

Text Solution

Verified by Experts

The correct Answer is:
D
PQ corresponds to increase in vapour pressure of solvent with temperature and XY corresponds to increase in vapour pressure of solution with temperature . `DeltaT` is the elevation in boiling point of a solution.
