The Haber process and the use of NPK fertilisers
Question
- A. Because the reaction is carried out at very low temperatures.
- B. Because the reaction is carried out in a closed system with no removal of products.
- C. Because the reaction can proceed in both directions, producing and consuming ammonia.
- D. Because the reaction uses a catalyst that breaks down ammonia.
Answer
The correct option is Because the reaction can proceed in both directions, producing and consuming ammonia.. This answer is correct because it matches the approved learning objective to describe ammonia formation as a reversible reaction. (Chemistry only) in the subtopic The Haber process.
Explanation
The correct option is Because the reaction can proceed in both directions, producing and consuming ammonia.. Because the reaction can proceed in both directions, producing and consuming ammonia. is correct because it directly supports the approved learning objective to describe ammonia formation as a reversible reaction. (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
Confusing Reaction Direction
Students often describe the formation of ammonia in the Haber process as a one-way reaction, not recognizing it as reversible.
Emphasize that ammonia formation is a reversible reaction, meaning it can proceed in both forward and reverse directions.
