Le Chatelier PressureEasyQuestion 600404
Question
For N₂ + 3H₂ ⇌ 2NH₃ (Δn = 2−4 = −2), increasing pressure will:
- AShift equilibrium to the left
- BShift equilibrium to the rightCorrect
- CHave no effect
- DDecrease K
Correct answer
Shift equilibrium to the right
Explanation
Increasing pressure shifts equilibrium toward fewer moles of gas (Δn < 0). Here Δn = −2, so pressure increase favours NH₃ production (right shift).
