The Haber process and the use of NPK fertilisers
Question
- A. It shifts the equilibrium to favor the formation of reactants.
- B. It has no effect on the equilibrium position.
- C. It shifts the equilibrium to favor the formation of products.
- D. It increases the rate of the reverse reaction.
Answer
The correct option is It shifts the equilibrium to favor the formation of products.. This answer is correct because it matches the approved learning objective to explain why cooling allows ammonia to liquefy and be removed from the reaction mixture. (Chemistry only) in the subtopic The Haber process.
Explanation
The correct option is It shifts the equilibrium to favor the formation of products.. It shifts the equilibrium to favor the formation of products. is correct because it directly supports the approved learning objective to explain why cooling allows ammonia to liquefy and be removed from the reaction mixture. (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
Cooling and Ammonia Liquefaction
Students often think that cooling ammonia directly causes it to form from the gases.
Emphasize that cooling allows the already formed ammonia gas to liquefy and be separated from unreacted gases.
