The Haber process and the use of NPK fertilisers
Question
- A. It is a one‑way reaction that permanently consumes nitrogen and hydrogen.
- B. It is a reversible reaction that can reach a dynamic equilibrium.
- C. It is a combustion reaction that releases heat.
- D. It is a decomposition reaction that breaks down ammonia into nitrogen and hydrogen.
Answer
The correct option is It is a reversible reaction that can reach a dynamic equilibrium.. 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 It is a reversible reaction that can reach a dynamic equilibrium.. It is a reversible reaction that can reach a dynamic equilibrium. 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.
