Raoult’s Law And Phase Equilibria
If two liquids A and B form minimum boiling azeotrope at some specific composition then.
Vapour pressure of solution remains the same because more number of molecules of liquids A and B can escape from the solution.
A–B interactions are weaker than those between A–A or B–B.
Vapour pressure of solution decreases because less number of molecules of only one of the liquids escape from the solution.
A–B interactions are stronger than those between A–A or B–B.
Which of the following pairs of liquids when mixed would give a higher boiling point that predicted by Raoult’s law?
Propane and trichloromethane.
Propanol and ethanol.
Nitric acid and water.
Hexane and water.
Which of the following pairs of liquids, on mixing will form a solution that will deviate negatively from Raoult’s law ?
Propanone and trichloromethane.
Methanol and water.
Ethanol and water.
Propan-2-ol and propan-1-ol.
