📖 Le Chatelier's Principle
The system is currently balanced according to the Haber compromise.
Temperature
The reaction is exothermic. Increasing heat shifts equilibrium left.
Pressure
Higher pressure favours the side with fewer gas molecules (2 mol NH₃ vs 4 mol reactants).
The Haber Compromise
Engineers maximise profit, not just yield. 450°C ensures a fast enough rate to be commercially viable. High pressures are expensive and dangerous.
