SampleChemistry· MCQ+4 / -1

Consider the given plots of vapour pressure (VP) vs temperature (T/K). Which amongst the following options is the correct graphical representation showing

Δ T_{f}

, the depression in the freezing point of a solvent in a solution?

Four candidate plots, labelled 1 to 4, of vapour pressure on the vertical axis against temperature T/K on the horizontal axis. Each plot shows a curve for the liquid solvent, a curve for the solution and a steep curve for the frozen solid, with a horizontal arrow marking the freezing-point depression between Tf of the solution and Tf-degree of the pure solvent.

A. $1$
B. $2$
C. $3$
D. $4$
