In the reaction: N₂ (g) + 3H₂ (g) ⇌ 2NH₃ (g), what would increase the yield of ammonia?
Increasing the temperature
Decreasing the pressure
Increasing the pressure
Adding a catalyst
Explanation
Increasing pressure favors the side with fewer moles of gas (the product side), thus increasing the yield of ammonia.
