The production of ammonia by the haber process may be represented by the equilibrium equation N₂(g) + 3H₂(g) ↔ 2NH₃ ∆H = -22KJ. Therefore the production of ammonia will be favoured by?

• A only high pressure
• B only high temperature
• C a combination of high temperature and low pressure
• D a combination of low temperature and high pressure
• E low pressure
