Expert Answer

Step 1

According to Raoult’s law, when in a binary solution, there are present two volatile liquids, than vapor pressure of each liquid is directly proportional to its mole fraction.

 

The solution that does not follow the Raoult’s law over the complete range of concentration is known as non-ideal solution.

Step 2

The positive and negative deviations are due to the intermolecular forces between solute and solvent in a solution.

 

The interactions between chloroform and acetone are stronger because ...
