Use this lesson plan for 14–16 year olds to practise interpreting rate of reaction graphs, revising factors such as concentration, temperature and surface area.

In this activity, pre‑drawn graphs are chosen by students to match the most likely outcomes from different reaction conditions for the reaction between calcium carbonate and hydrochloric acid. The graphs are a prop to help students check and reinforce what they have learnt about factors affecting rates of reaction, including concentration, temperature and surface area of solid reactants.

The resource would be particularly useful for checking on learning towards the end of teaching this topic or when revising for an external assessment.
