Question
What are the two raw materials used in the Haber process for the industrial manufacture of ammonia?
Answer
The two raw materials used in the Haber process are nitrogen and hydrogen.
Explanation
A strong answer should directly address the approved learning objective to describe purified nitrogen and hydrogen passing over an iron catalyst. (Chemistry only). This question belongs to The Haber process within The Haber process and the use of NPK fertilisers, so the response should use that exact curriculum context rather than a generic statement. The answer is correct when it names the key idea, explains the link to chemistry only, and keeps the wording specific to AQA GCSE revision.
Common mistake
Common Misunderstanding of the Haber Process
Students often confuse the role of the iron catalyst with the reactants in the Haber process, thinking that the catalyst is a reactant.
Remember that the iron catalyst is not consumed in the reaction; it only speeds up the process of ammonia formation without being part of the chemical equation.
