(A)-(III), (B)-(I), (C)-(IV), (D)-(II)

(A)-(II), (B)-(III), (C)-(I), (D)-(IV)

(A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Correct Answer:

(A)-(III), (B)-(I), (C)-(IV), (D)-(II)

Explanation:

List-I	List-II	Explanation
(A) Raoult's Law	(III) $p = x_1p_1^\circ + x_2p_2^\circ$	Raoult's law relates total vapor pressure of an ideal liquid mixture to the mole fractions and vapor pressures of the components.
(B) Henry's Law	(I) $p = k_H \cdot x$	Henry’s law states that the partial pressure of a gas in a liquid is proportional to its mole fraction.
(C) Elevation of Boiling Point	(IV) $\Delta T_b = K_b \cdot m$	Elevation in boiling point is directly proportional to molality of the solute in the solution.
(D) Depression in Freezing Point	(II) $\Delta T_f = K_f \cdot m$	Depression in freezing point is also directly proportional to the molality of solute particles.
