Expert Answer:

Dear Student
Osmotic pressure is the pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane.
 

A few examples of non-ideal solutions showing positive deviations are Acetone + Carbon disulphide, Acetone + Ethyl alcohol, Acetone + Benzene, Methyl alcohol + Water, Ethyl alcohol + Water. In mixtures showing a positive deviation from Raoult's Law, the vapour pressure of the mixture is always higher than you would expect from an ideal mixture

 
We hope that clarifies your query.
