The Haber process and the use of NPK fertilisers
Question
- A. It is used to produce potassium salts
- B. It is a source of nitrogen
- C. It enhances phosphorus availability
- D. It acts as a stabilizer
Answer
The correct option is It is a source of nitrogen. This answer is correct because it matches the approved learning objective to explain that ammonia can be used to make nitrogen-based fertilisers. (Chemistry only) in the subtopic The Haber process.
Explanation
The correct option is It is a source of nitrogen. It is a source of nitrogen is correct because it directly supports the approved learning objective to explain that ammonia can be used to make nitrogen-based fertilisers. (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.
