Question
Match the following equilibria with the corresponding condition:
| Column I | Column II |
| (i) Liquid ⇌ Vapour | (a) Saturated solution |
| (ii) Solid ⇌ Liquid | (b) Boiling point |
| (iii) Solid ⇌ Vapour | (c) Sublimation point |
| (iv) Solute (s) ⇌ Solute (solution) | (d) Melting point Unsaturated solution |
Solution
| Column I | Column II |
| (i) Liquid ⇌ Vapour | (b) Boiling point |
| (ii) Solid ⇌ Liquid | (d) Melting point Unsaturated solution |
| (iii) Solid ⇌ Vapour | (c) Sublimation point |
| (iv) Solute (s) ⇌ Solute (solution) | (a) Saturated solution |
Explanation:
(i) Liquid ⇌ Vapour equilibrium exists at the boiling point.
(ii) Solid ⇌ Liquid equilibrium exists at the melting point.
(iii) Solid ⇌ Vapour equilibrium exists at the sublimation point.
(iv) Solute (s) ⇌ Solute (solution) equilibrium exists in saturated solution.
