The Haber process and the use of NPK fertilisers
Question
- A. To maximize the amount of ammonia produced
- B. To minimize the overall production costs
- C. To ensure the reaction occurs at a faster rate
- D. To maintain a constant temperature
Answer
The correct option is To minimize the overall production costs. This answer is correct because it matches the approved learning objective to explain how industrial conditions are chosen by considering raw material availability, energy costs, equilibrium position and rate. (HT only; Chemistry only; WS 3.5, 3.8) in the subtopic The Haber process.
Explanation
The correct option is To minimize the overall production costs. To minimize the overall production costs is correct because it directly supports the approved learning objective to explain how industrial conditions are chosen by considering raw material availability, energy costs, equilibrium position and rate. (HT only; Chemistry only; WS 3.5, 3.8). 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
Understanding Industrial Conditions
Students often confuse the factors affecting industrial conditions in the Haber process, thinking they are all equally important.
Focus on how raw material availability, energy costs, equilibrium position, and rate each play distinct roles in determining the optimal conditions for the Haber process.
