Question

19. Which of the following is/are correct statement(s) about the Raoult's law applied to a solution of non-
volatile solute?
(A) Vapour pressure of solution is proportional to mole fraction of solute.
(B) Vapour pressure of solution is proportional to the mole fraction of solvent.
(C) Relative lowering of Vapour pressure = mole fraction of solute
(D) Lowering of vapour pressure is proportional to the mole fraction of solute.​

Answer 1

Answer:

Established by French chemist François-Marie Raoult in 1887, it states that the partial pressure of each component of an ideal mixture of liquids is equal to the vapor pressure of the pure component multiplied by its mole fraction in the mixture.

Answer 2

Vapour pressure of solution is proportional to mole fraction of solute V.P of solution is proportional to the mole fraction of solvent Relative lowering of V.P = mole fraction of solvent Lowering of vapour pressure is proportional to the mole fraction of solute.
