The Haber process and the use of NPK fertilisers
Question
- A. 200 degrees Celsius
- B. 450 degrees Celsius
- C. 600 degrees Celsius
- D. 800 degrees Celsius
Answer
The correct option is 450 degrees Celsius. This answer is correct because it matches the approved learning objective to distinguish rate considerations from equilibrium yield considerations in the Haber process. (HT only; Chemistry only) in the subtopic The Haber process.
Explanation
The correct option is 450 degrees Celsius. 450 degrees Celsius is correct because it directly supports the approved learning objective to distinguish rate considerations from equilibrium yield considerations in the Haber process. (HT only; 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 Rate and Yield
Students often confuse the concepts of rate of production and equilibrium yield in the Haber process, thinking they are the same.
To fix this, students should clearly define rate as how quickly products are formed and equilibrium yield as the maximum amount of product that can be obtained at equilibrium.
