Remember the Haber conditions with HINT:
- Hydrogen from natural gas (methane + steam)
- Iron catalyst
- Nitrogen from air
- Temperature ~450°C, pressure ~200 atm (Two-Hundred)
And remember: "Low T, high P = more NH₃" — but industry uses a compromise because of rate and cost.
This memory aid covers Memory Aid — HINT within The Haber Process & Fertilisers for GCSE Chemistry. Revise The Haber Process & Fertilisers in Rates of Reaction for GCSE Chemistry with 6 exam-style questions and 6 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 10 of 13 in this topic. Use it for quick recall, then test yourself straight afterwards so the memory aid becomes usable in an answer.
