Lesson details
Key learning points
- In a reversible reaction the desired product needs to be continuously removed from the reaction.
- Natural gas is a feedstock for industrial production of ammonia.
- Hydrogen, one of the raw materials in ammonia production, is produced from natural gas and steam.
- In industry, the Haber process is typically performed at 150-300 atmospheres, 400-450°C, with an iron catalyst.
- Ammonia production is energy-intensive and releases large amounts of carbon dioxide, contributing to global emissions.
Keywords
Natural gas - A mixture of gases which are rich in hydrocarbons, consisting largely of methane.
Feedstock - Refers to the raw materials used in chemical processes to produce other substances.
Raw material - The starting materials used to make products are known as the raw materials.
Haber process - An industrial method for producing ammonia from nitrogen and hydrogen.
Common misconception
Students find it difficult to understand why continuous removal of ammonia is required to increase yield.
Highlight that the Haber Process is a dynamic equilibrium. If ammonia is not continuously removed, the equilibrium will shift back towards the reactants, reducing the yield.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
