The Haber process and the use of NPK fertilisers
Question
- A. To prevent the reaction from becoming irreversible.
- B. To shift the equilibrium towards more ammonia production.
- C. To increase the reaction temperature.
- D. To recycle unreacted nitrogen and hydrogen.
Answer
The correct option is To shift the equilibrium towards more ammonia production.. 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 To shift the equilibrium towards more ammonia production.. To shift the equilibrium towards more ammonia production. 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.
