The Haber process and the use of NPK fertilisers
Question
- A. Oxygen and carbon dioxide
- B. Nitrogen and hydrogen
- C. Ammonia and water
- D. Methane and sulfur
Answer
The correct option is Nitrogen and hydrogen. This answer is correct because it matches the approved learning objective to describe purified nitrogen and hydrogen passing over an iron catalyst. (Chemistry only) in the subtopic The Haber process.
Explanation
The correct option is Nitrogen and hydrogen. Nitrogen and hydrogen is correct because it directly supports the approved learning objective to describe purified nitrogen and hydrogen passing over an iron catalyst. (Chemistry only). This belongs to the subtopic The Haber process within The Haber process and the use of NPK fertilisers, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from The Haber process.
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.
