Question

Consider the reaction below. 2 Upper N Upper H Subscript 3 (g) Baseline double headed arrow Upper N Subscript 2 (g) Baseline + 3 Upper H Subscript 2 (g). What is the most likely effect to the forward reaction if there is an increase in pressure on this reaction? The reactant surface area increases. The reaction rate decreases. The reaction is not affected at all. The reaction stops completely.

Answer 1

Increasing the pressure on the ammonia synthesis reaction leads to a shift in equilibrium towards the forward reaction, favoring the production of ammonia to reduce pressure.

Step-by-step explanation:

When pressure is increased on the equilibrium reaction of ammonia synthesis (2 NH₃ (g) ⇌ N₂ (g) + 3 H₂ (g)), according to Le Chatelier's principle, the system adjusts to counteract the change in conditions. In this case, the forward reaction is favored because it produces fewer moles of gas (2 moles of NH₃) compared to the reverse reaction which produces 4 moles of gas (1 mole of N₂ and 3 moles of H₂). Thus, an increase in pressure will shift the equilibrium towards the production of ammonia, momentarily speeding up the forward reaction until a new equilibrium is achieved.
