The Haber process and the use of NPK fertilisers
Question
- A. It increases the temperature of the reaction
- B. It provides the necessary hydrogen
- C. It speeds up the reaction without being consumed
- D. It absorbs excess ammonia
Answer
The correct option is It speeds up the reaction without being consumed. This answer is correct because it matches the approved learning objective to describe the Haber process as the industrial manufacture of ammonia. (Chemistry only) in the subtopic The Haber process.
Explanation
The correct option is It speeds up the reaction without being consumed. It speeds up the reaction without being consumed is correct because it directly supports the approved learning objective to describe the Haber process as the industrial manufacture of ammonia. (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
Misunderstanding the Haber Process
Students often confuse the Haber process with other methods of ammonia production, thinking it involves only one raw material.
Remember that the Haber process specifically uses nitrogen and hydrogen as raw materials to produce ammonia.
