MHT CET Chemistry question

For a dilute solution, the Raoult's law states that,

(A)The lowering of vapour pressure is equal to mole fraction of solute
(B)The relative lowering of vapour pressure is equal to mole fraction of soluteCorrect
(C)The relative lowering of vapour pressure is proportional to amount of solute
(D)The vapour pressure of the solution is equal to mole fraction of the solvent

Answer: (B)

Solution

Raoult's law gives , the relative lowering equals the solute mole fraction; the absolute lowering (a) and the vapour pressure itself (d)
