STANDARD Physics Thermodynamic Processes Match the Following Question
Match the columns with and mark the appropriate choice.
| Column-I | Column-II |
|---|---|
| (A) Exothermic | (i) H = 0, ΔU = 0 |
| (B) Spontaneous | (ii) G = 0 |
| (C) Cyclic process | (iii) H is negative |
| (D) Equilibrium | (iv) G is negative |
(A) → (ii), (B) → (iii), (C) → (i), (D) → (iv)
(A) → (iv), (B) → (i), (C) → (iii), (D) → (ii)
(A) → (i), (B) → (ii), (C) → (iv), (D) → (iii)
(A) → (iii), (B) → (iv), (C) → (i), (D) → (ii)
Correct Answer
Detailed Explanation
Exothermic reactions have negative enthalpy change (H is negative). Spontaneous reactions have negative Gibbs free energy (G is negative). Cyclic processes have zero enthalpy and internal energy change (H = 0, ΔU = 0). Equilibrium processes have zero Gibbs free energy change (G = 0).
