Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit covers corrosion, prevention methods, and properties of alloys, ceramics, polymers, and metals. It explores industrial processes like the Haber process, fertiliser production, reaction rates, yields, atom economy, and the trade-offs involving conditions and equilibrium.
Lesson Summary
You will learn to describe the Haber Process for the production of ammonia, explain the significance of equilibrium in this industrial process, and describe the conditions used.
Key Notes
- 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.
Vocabulary To Learn
- 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 Mistakes To Avoid
- Students find it difficult to understand why continuous removal of ammonia is required to increase yield.
3 Quick Questions (With Answers)
1. Explain the scientific idea in this lesson using two key 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.
2. Define this scientific word and use it in context. 'natural gas'
A mixture of gases which are rich in hydrocarbons, consisting largely of methane. Include the word in a full scientific explanation, not as a single label.
3. Correct this common scientific misunderstanding.
Mistake: Students find it difficult to understand why continuous removal of ammonia is required to increase yield. Correction: 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.
