Rate of reaction
Downloads can take a few minutes, especially for larger files or slower connections.

Why this why now
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.
Prior knowledge requirements
- 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.

Rate of reaction
This unit explores factors influencing reaction rates, including temperature, concentration, surface area, and catalysts. It covers using models and theories to develop hypotheses, planning and conducting experiments safely, selecting appropriate techniques, and presenting and translating data.
