In which direction does the equilibrium (exothermic forward) shift when pressure is increased?
Answer and explanation
Correct answer: B. Towards the ammonia (fewer gas moles)
- Step 1: By Le Chatelier's principle, a higher pressure favours the side with fewer moles of gas: 2 mol instead of 4 mol.
Answer
Towards the ammonia (fewer gas moles).
Why not the others: Towards the nitrogen and hydrogen, It does not shift and It shifts only if the temperature falls do not fit.
