18.1 Rates of reaction

In this OCR A Level Chemistry video, award-winning science teacher Dr. David Boyce expertly explores the topic of rates of reactions. Dr. Boyce begins by introducing the fundamental factors that affect reaction rates, including concentration, temperature, surface area, and catalysts. He then delves into interpreting concentration-time graphs, explaining how to determine the rate of reaction from the gradient of these graphs. Dr. Boyce illustrates how steeper slopes indicate faster reactions and how the graphs change under different conditions. The video includes practical examples and visual aids to help students understand how to calculate and compare reaction rates from the graphs. This comprehensive and engaging video is designed to enhance students' understanding of reaction kinetics and their ability to analyse and interpret experimental data effectively.
