Question
What are the main raw materials used in the Haber process for the industrial manufacture of ammonia?
Answer
The main raw materials used in the Haber process are nitrogen and hydrogen. Nitrogen is typically sourced from the air, while hydrogen can be obtained from methane or natural gas through steam reforming.
Explanation
A strong answer should directly address the approved learning objective to interpret graphs of reaction conditions versus rate. (HT only; Chemistry only; MS 1a, 1c). 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
Misinterpreting Graphs
Students often confuse the axes on graphs of reaction conditions versus rate, leading to incorrect interpretations of how changes in conditions affect the rate of reaction.
Carefully label and review the axes of the graph, ensuring you understand which variable is being plotted against which. Remember that the x-axis typically represents the reaction conditions, while the y-axis represents the rate.
