By the end you’ll be able to

Calculate the mean rate of reaction from the amount of reactant used or product formed over time, and (HT) find the rate at a point by drawing a tangent and calculating its gradient
Explain the effects of concentration, gas pressure, surface area, temperature and catalysts on rate using collision theory and activation energy
Required practical: investigate how concentration affects rate by measuring the volume of gas produced or a change in colour or turbidity

(HT) Use Le Chatelier’s principle to predict how changing concentration, temperature or pressure shifts the position of equilibrium; (Edexcel, Cambridge) apply it to the Haber process
