A PowerPoint summarising the whole topic on the rate and extent of chemical change and organic chemistry in GCSE AQA Combined Science chemistry. The main sources used included BBC Bitesize, the CGP revision guide, and Freesciencelessons on YouTube. I am not claiming that all the content on this PowerPoint is entirely my own. As mentioned, I have used certain sources, rephrased and changed them to help me in my own revision at GCSE. The images, diagrams included, have been sourced online, or from the sources mentioned above. However, the layout is indeed my own. Please add or remove anything you may need, but please do not reupload anywhere. Thank you.
