JEE Main Chemistry question

For dilute solution Raoult's law states that [MP PET 2004]

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

Answer: (A)

Solution

Raoult's law states precisely that the relative lowering of vapour pressure, , equals the mole fraction of the solute, not the absolute lowering (B) and
