In the ammonia synthesis reaction, N2 + 3H2 ⇌ 2NH3 + 22.4 kcal, the formation of NH3 will be favoured by___________________?
Correct answer: A. Both low temperature and high pressure
- A. Both low temperature and high pressure
- B. Low pressure
- C. Low temperature only
- D. High temperature
Explanation
Ammonia formation is exothermic, so lowering temperature favours it, while the reaction changes four gas moles into two and therefore high pressure favours the product side. Both conditions are required for higher equilibrium ammonia yield.
