Question

State raoult law for a solution containing non volatile solute what type of deviation from raoul's law is shown by a solution of chloroform and acetone and why

Answer 1

The vapour pressure of a solution containing non volatile solute is equal to the product of the mole fraction of the solvent in the solution and vapor pressure of pure solvent

The solution of chloroform and acetone gives negative deviation because the partial pressure of each component and the resultant total vapour pressure are less than the pressure expected on the basis of Raoult's Law
