Consider the given plots of vapour pressure (VP) vs temperature (T/K). Which amongst the following options is correct graphical representation showing $\Delta {{\rm{T}}_{\rm{f}}}$, depression in the freezing point of a solvent in a solution?
Options
A
B
C
D
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
On adding non-volatile solute in a solvent, the freezing point of solution decreases.
${{\rm{T}}_{\rm{f}}} < {\rm{T}}_{\rm{f}}^0$
F.P. of solution < F.P. of pure solvent
Also V.P. of solution decreases on adding non-volatile solute in a solvent.
