Which of the following deviations from Raoult's law is associated with the formation of a maximum boiling azeotrope?

An aqueous solution is 1.0 molal in KI. Which change will cause the vapour pressure of solution to increase :

For dilute solution Raoult’s law states that

Benzene and toluene form nearly ideal solutions. At $25^\circ C$, the vapour pressure of benzene is 75 torr and that of toluene is 22 torr. The partial vapour pressure of benzene at $20^\circ C$ for a solution containing 78 g of benzene and 46 g of toluene in torr is

A solution containing components $A$ and $B$ follows Raoult’s law

An aqueous solution of methanol in water has vapour pressure

The relative lowering of vapour pressure produced by dissolving 71.5 g of a substance in 1000 g of water is 0.00713. The molecular weight of the substance will be :

For a mixture of two liquids to behave ideally, the interactions between unlike molecules should be:

At $80^\circ C$, the vapour pressure of pure liquid 'A'is 520 mm Hg and that of pure liquid 'B' is 1000 mm Hg. If a mixture of solution 'A'\;{\rm{and}}\;'B' boils at $80^\circ C$ and 1 atm pressure, the amount of 'A' in the mixture is : (1 atm = 760 mm Hg)

A binary solution of two volatile liquids A and B deviates negatively from Raoult's Law. At a specific composition, the total vapor pressure is minimum. Which of the following statements is FALSE regarding this specific composition?

For an ideal binary liquid solution with $P_A^ \circ > P_B^ \circ$ which relation between ${X_A}$ (mole fraction of A in liquid phase) and ${Y_A}$ (mole fraction of A in vapour phase) is correct, ${X_B}$ and ${Y_B}$ are mole fraction of B in liquid and vapour phase respectively :
