In the graph plotted between vapour pressure $$(V.P.)$$ and temperature $$(T),$$
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 $$\Delta T$$ is depression in freezing point
B.
$$PQ$$ is the curve for solution, $$XY$$ is the curve for solvent and $$\Delta T$$ is elevation in boiling point
C.
$$PQ$$ is the curve for solvent, $$XY$$ is the curve for solution and $$\Delta T$$ is molal elevation in boiling point
D.
$$PQ$$ is the curve for solvent, $$XY$$ is the curve for solution and $$\Delta T$$ is elevation in boiling point.
Answer :
$$PQ$$ is the curve for solvent, $$XY$$ is the curve for solution and $$\Delta T$$ is elevation in boiling point.
Solution :
$$PQ$$ corresponds to increase in vapour pressure of solvent with temperature and $$XY$$ corresponds to increase in vapour pressure of solution with temperature. $$\Delta T$$ is the elevation in boiling point of a solution.
$$PQ$$ corresponds to increase in vapour pressure of solvent with temperature and $$XY$$ corresponds to increase in vapour pressure of solution with temperature. $$\Delta T$$ is the elevation in boiling point of a solution.
