1. Raoult’s law

2. Positive deviation from Raoult’s law. In a solution formed by adding CS2 to acetone, the dipolar interactions between solute-solvent molecules are weaker than the respective interactions among the solute-solute and solvent-solvent molecules. Thus, the escaping tendency of the particles increases and the solution shows +ve deviation.
