The Haber process and the use of NPK fertilisers
Question
- A. NPK fertilisers are made from ammonia and other compounds
- B. The Haber process does not use nitrogen
- C. NPK fertilisers are produced at lower temperatures
- D. The Haber process only produces phosphates
Answer
The correct option is NPK fertilisers are made from ammonia and other compounds. This answer is correct because it matches the approved learning objective to distinguish NPK fertiliser manufacture from the Haber process that produces ammonia in the subtopic Production and uses of NPK fertilisers.
Explanation
The correct option is NPK fertilisers are made from ammonia and other compounds. NPK fertilisers are made from ammonia and other compounds is correct because it directly supports the approved learning objective to distinguish NPK fertiliser manufacture from the Haber process that produces ammonia. This belongs to the subtopic Production and uses of NPK fertilisers 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 Production and uses of NPK fertilisers.
Common mistake
Confusing Processes
Students often confuse the NPK fertiliser manufacture process with the Haber process, thinking they are the same.
Remember that the Haber process specifically produces ammonia, while NPK fertiliser manufacture involves combining nitrogen, phosphorus, and potassium compounds.
