Answer

To solve the matching question, we will analyze each reaction provided in List-I and determine the effects of temperature and pressure based on Le Chatelier's principle.

### Step-by-Step Solution:

1. **Identify the reactions and their characteristics:**
- **P:** Formation of ammonia by Haber’s process
- **Q:** Formation of SO₃ in the contact process for the manufacture of H₂SO₄
- **R:** Formation of NO in the Birkeland-Eyde process for the manufacture of HNO₃
- **S:** Formation of NO₂(g) by the reaction NO(g) + O₃ ⇌ NO₂(g) + O₂(g) + 200 kJ

2. **Analyze Reaction P (Haber's Process):**
- Reaction: N₂(g) + 3H₂(g) ⇌ 2NH₃(g) (exothermic)
- **Effect of Temperature:** Increasing temperature decreases the yield of ammonia (shift left).
- **Effect of Pressure:** Increasing pressure increases the yield (shift right).
- **Match:** Decrease in temperature (2) and increase in pressure (4). So, P matches with (2, 4).

3. **Analyze Reaction Q (Contact Process):**
- Reaction: 2SO₂(g) + O₂(g) ⇌ 2SO₃(g) (exothermic)
- **Effect of Temperature:** Decrease in temperature increases the yield of SO₃ (shift right).
- **Effect of Pressure:** Increasing pressure increases the yield (shift right).
- **Match:** Decrease in temperature (2) and increase in pressure (4). So, Q also matches with (2, 4).

4. **Analyze Reaction R (Birkeland-Eyde Process):**
- Reaction: N₂(g) + O₂(g) ⇌ 2NO(g) (endothermic)
- **Effect of Temperature:** Increasing temperature increases the yield of NO (shift right).
- **Effect of Pressure:** No effect on pressure since the number of moles of gas is the same on both sides.
- **Match:** Increase in temperature (1). So, R matches with (1).

5. **Analyze Reaction S (Formation of NO₂):**
- Reaction: NO(g) + O₃(g) ⇌ NO₂(g) + O₂(g) + 200 kJ (exothermic)
- **Effect of Temperature:** Decrease in temperature increases the yield of NO₂ (shift right).
- **Effect of Pressure:** No effect on pressure since the number of moles of gas is the same on both sides.
- **Match:** Decrease in temperature (2). So, S matches with (2).

### Final Matching:
- P: (2, 4)
- Q: (2, 4)
- R: (1)
- S: (2)

### Summary of Matches:
- P matches with (2, 4)
- Q matches with (2, 4)
- R matches with (1)
- S matches with (2)
