A is true but R is false (2024)

Assertion:Lowering of vapour pressure is not dependent on the number of species present in the solution.
Reason : Lowering of vapour pressure and relative lowering of vapour pressure are colligative properties

02:09

Lowering of vapour pressure on dissolving a non-volatile solute in a liquid is a colligative property.

04:28

A: Lowering of vapour pressure depends upon concentration of solute. R: Relative lowering of vapour pressure is a colligative property

03:59

Explain with vapour pressure-temperature curves that the freezing point of a solvent is lowered by dissolving a nonvolatile solute into it. Give reason for such lowering of freezing of solvent

07:00

The vapour pressure lowering of a solvent is proportional to

Text Solution

Why vapour pressure of a solvent is lowered by dissolving a nonvolatile solute into it?

03:26

If P∘ the vapour pressure of a pure solvent and P is the vapour pressure of the solution prepared by dissolving a non volatile solute in it. The mole fraction of the solvent XA is given by:

01:24

Statement-I: Relative lowering of vapour pressure is equal to mole fraction of the solvent.
Because
Statement-II: Relative lowering of vapour pressure is a colligative property.
