The Haber process and the use of NPK fertilisers

Question

A. It is a raw material for making nitrogen-based fertilisers.
B. It is used to neutralize acids in the process.
C. It acts as a catalyst in the reactions.
D. It is the final product of the fertiliser production.

Answer

The correct option is It is a raw material for making nitrogen-based fertilisers.. This answer is correct because it matches the approved learning objective to compare industrial fertiliser production with laboratory preparation of similar compounds using given information. (Chemistry only) in the subtopic Production and uses of NPK fertilisers.

Explanation

The correct option is It is a raw material for making nitrogen-based fertilisers.. It is a raw material for making nitrogen-based fertilisers. is correct because it directly supports the approved learning objective to compare industrial fertiliser production with laboratory preparation of similar compounds using given information. (Chemistry only). This belongs to the subtopic Production and uses of NPK fertilisers 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 Production and uses of NPK fertilisers.

Common mistake

Misunderstanding Production Methods

Students often confuse the methods of industrial fertiliser production with laboratory preparation, thinking they are the same process.

To fix this, students should focus on the differences in scale, raw materials used, and the conditions under which each method operates.
