Answer 1

Answer:

Explanation:

Hence according to raulat s law when a non volatile solute is added in the pure solvent it accumulates the surface of the solvent and leads to relative decrease in the vapour pressure of the solution which leads to elevation of boiling point of solution and depression in the freezing point of solution
