In the chemical reaction, N ₂+3 H ₂ 2 NH ₃ at equilibrium point.
Options
- Aequal volumes of N ₂ and H ₂ are reacting.
- Bequal manes of N ₂ and H ₂ are reacting.
- Cthe reaction has stopped.
- Dthe same amount of ammonia is formed, as it is decomposed into N ₂ and H ₂ .
Correct answer
D. the same amount of ammonia is formed, as it is decomposed into N ₂ and H ₂ .
Step-by-step solution
The chemical reaction N ₂ + 3 H ₂ 2 NH ₃ represents a reversible process at equilibrium. At equilibrium, the rate of the forward reaction (formation of NH ₃ ) is equal to the rate of the backward reaction (decomposition of NH ₃ into N ₂ and H ₂ ). This implies that the amount of ammonia being formed per unit time is exactly equal to the amount of ammonia being decomposed per unit time, maintaining constant concentrations of all species involved. Therefore, the condition at equilibrium is that the rate of formation
