Cambridge IGCSE Chemistry Topic 6 REVISION (Chemical energetics)

This is an engaging revision lesson which uses a range of exam questions, understanding checks, quiz tasks and quiz competitions to enable students to assess their understanding of the content within topic 6 (Chemical energetics) of the Cambridge IGCSE Chemistry (0620) specification. The lesson covers the content in both the core and supplement sections of the specification and therefore can be used with students who will be taking the extended papers as well as the core papers.

The specification points that are covered in this revision lesson include:

CORE

• Describe the meaning of exothermic and endothermic reactions
• Interpret energy level diagrams showing exothermic and endothermic reactions
• Describe the release of heat energy by burning fuels
• State the use of hydrogen as a fuel

SUPPLEMENT

• Describe bond breaking as an endothermic process and bond forming as an exothermic process
• Draw and label energy level diagrams for exothermic and endothermic reactions using data provided
• Calculate the energy of a reaction using bond energies
• Describe the use of hydrogen as a fuel reacting with oxygen to generate electricity in a fuel cell.

The students will thoroughly enjoy the range of activities, which include quiz competitions such as “E NUMBERS” where they have to recognise the differences between endothermic and exothermic reactions whilst crucially being able to recognise the areas of this topic which need their further attention. This lesson can be used as revision resource at the end of the topic or in the lead up to mocks or the actual GCSE exams
