Match List-I with List-II:
| List-I (Process / State) | List-II (Thermodynamic Criterion) | ||
|---|---|---|---|
| A | Isolated system at equilibrium | I | \( \Delta G < 0 \) at constant \( T, p \) |
| B | Spontaneous process | II | \( \Delta S = 0 \) and entropy is maximum |
| C | Reversible process | III | \( S = 0 \) for pure crystal |
| D | Absolute zero (0 K) | IV | \( \Delta S_{\text{total}} = 0 \) |

Correct answer · Option 1
A-(II), B-(I), C-(IV), D-(III)
Explanation
At equilibrium for an isolated system \( \Delta S = 0 \) (A-II). Spontaneous: \( \Delta G < 0 \) (B-I). Reversible: \( \Delta S_{\text{total}} = 0 \) (C-IV). At 0 K: \( S = 0 \) (D-III).
