Question
Why is air considered a suitable source of nitrogen for the Haber process?
Answer
Air is considered a suitable source of nitrogen for the Haber process because it contains approximately 78% nitrogen, making it readily available for industrial use.
Explanation
A strong answer should directly address the approved learning objective to recall air as a source of nitrogen for the Haber process. (Chemistry only). This question belongs to The Haber process within The Haber process and the use of NPK fertilisers, so the response should use that exact curriculum context rather than a generic statement. The answer is correct when it names the key idea, explains the link to chemistry only, and keeps the wording specific to AQA GCSE revision.
Common mistake
Source of Nitrogen Confusion
Students often confuse air with nitrogen gas, thinking air is purely nitrogen.
Remember that air is a mixture of gases, with nitrogen being the main component but not the only one.
