The Haber process is carried out under specific conditions that represent a careful compromise:
| Condition | Value used | Why this value? |
|---|---|---|
| Temperature | ~450°C | Compromise between rate and yield |
| Pressure | ~200 atmospheres | Compromise between yield and cost/safety |
| Catalyst | Iron (with promoters) | Speeds up rate without affecting equilibrium |
The unreacted nitrogen and hydrogen are recycled back into the reactor so they are not wasted.
