The Haber process and the use of NPK fertilisers
Question
- A. It reduces the cost of raw materials
- B. It increases the efficiency of production
- C. It simplifies the chemical reactions
- D. It eliminates the need for ammonia
Answer
The correct option is It increases the efficiency of production. This answer is correct because it matches the approved learning objective to explain that industrial production of NPK fertilisers can use several raw materials and integrated processes. (Chemistry only) in the subtopic Production and uses of NPK fertilisers.
Explanation
The correct option is It increases the efficiency of production. It increases the efficiency of production is correct because it directly supports the approved learning objective to explain that industrial production of NPK fertilisers can use several raw materials and integrated processes. (Chemistry only). 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
Understanding Raw Materials
Students often think that NPK fertilisers are made from a single raw material.
Remember that NPK fertilisers can be produced using several raw materials and integrated processes.
