Answer & explanation
Correct answer: option 2
| 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. |
