Explain on a Particle Basis Why the Vapor
at a fixed temperature d/D is constant. Thus, osmotic pressure is directly proportional to the lowering of vapour pressure. … p/p ∝ π, i.e., Osmotic pressure is proportional to relative lowering of vapour pressure.

What will happen to the vapour pressure of a liquid if a small amount of non-volatile solute is added to it?

(b) When a non-volatile solute is dissolved in a liquid, the vapour pressure of liquid decreases and this lowering of vapour pressure is proportional to the mole fraction of solute added to it.

When non-volatile solute is added to solvent the vapour pressure of the solution decrease?

Addition of a non-volatile solute in a volatile ideal solvent decreases the vapour pressure of the solvent because if a non-volatile solute is added to the solvent temperature falls (since dissolution of a solute is an endothermic process) and thus, vapour pressure of the solution is lower than that of the pure solvent …
