IGCSE Chem Topic 7 – Chemical Reactions

Here are some key terms for this topic: Key Terms C7

GCSE Bitesize has revision pages (that take you through the topic), a test and an activity – click on Rates of Reaction.  GCSE s-cool – Rates of Reaction – revision notes & animations, practise exam questions and a revision summary. Skoool Chemistry – click on ‘6. Rates of Reaction’ for excellent lessons that take you through the topic; also a glossary of key terms.

Chemactive worksheets and answers just click on ‘Rates questions’.

For Doc Brown’s Chemistry quizzes, word-fills, crosswords and study notes go here and just scroll down.

This is a great power-point that also revises C6 Energy changes in chemical reactions:
