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?
only high pressure
only high temperature
a combination of high temperature and low pressure
a combination of low temperature and high pressure
low pressure
