Question

State Raoult's law. How is it formulated for solutions of non-volatile solutes ?

Answer 1

Raoult's law for solution of non-volatile solution : The relative lowering of vapour pressure for a solution is equal to the mole fraction of solute when solvent alone is volatile.

Answer 2

Answer:The vapour pressure of a solution of a non-volatile solute is equal to the vapour pressure of the pure solvent at that temperature multiplied by its mole fraction.

Explanation:

Raoult's law states that a solvent's partial vapour pressure in a solution (or mixture) is equal or identical to the vapour pressure of the pure solvent multiplied by its mole fraction in the solution.The vapour pressure of a solution of a non-volatile solute is equal to the vapour pressure of the pure solvent at that temperature multiplied by its mole fraction.
