KS3 & KS4 science curriculum

This unit builds on pupils’ prior learning from Energy changes in reactions, where they explored how energy is absorbed or released during chemical reactions. It deepens their understanding by focusing on the rate of reaction, examining factors such as temperature, concentration, and catalysts that influence how quickly reactions occur. This prepares pupils for the next unit, Industrial chemistry, where they will apply their knowledge to explore how reaction rates and energy changes are optimised in large-scale chemical processes, reinforcing practical applications of chemistry in industry.

1. The rate of a chemical reaction: including graphs
2. Appropriate equipment for measuring the rate of a reaction
3. Collision theory
4. Surface area and rate: practical
5. Surface area and rate: analysis
6. Concentration and rate: practical using gas collection method
7. Concentration and rate: practical using end point method
8. Concentration and rate: analysis
9. Temperature and rate: practical
10. Evaluating methods for measuring the rate of reaction
11. Catalysts and rate

• The neutralisation reaction is: base + acid ⭢ salt + water
• Metal carbonate + acid ⭢ salt + water + carbon dioxide
• Oxygen gas has a mass, as all gases do.
• When a metal reacts with acid bubbles may form, the temperature rise and the metal reduce in size or disappear.
• Characteristics of chemical reactions include changes in colour, bubbling, or a change of temperature.
• Bubbles appear when a gas is produced in a chemical reaction.
