The Haber process and the use of NPK fertilisers
Question
- A. Carbon dioxide
- B. Air
- C. Methane
- D. Oxygen
Answer
The correct option is Air. This answer is correct because it matches the approved learning objective to recall nitrogen and hydrogen as the raw materials for the Haber process. (Chemistry only) in the subtopic The Haber process.
Explanation
The correct option is Air. Air is correct because it directly supports the approved learning objective to recall nitrogen and hydrogen as the raw materials for the Haber process. (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 Raw Materials
Students often confuse nitrogen and hydrogen with other gases, such as oxygen or carbon dioxide, when recalling the raw materials for the Haber process.
To fix this, students should focus on memorizing that nitrogen and hydrogen are specifically the gases used in the Haber process, and practice distinguishing them from other gases.
