GCSE Chemistry 1-9 Topic 7 Revision Summary Video - Rates and Energy Changes

This is a revision summary video for topic 7 of the new 1-9 Chemistry GCSE – Rates of Reaction and Energy Changes - focusing on how you can investigate and explain rates of reaction in terms of collision theory and how you can work out if something is exothermic or endothermic.
I hope you find it useful!
