A student records the temperature of the surroundings during a reaction.
| Measurement | Temperature (°C) |
|---|---|
| Starting temperature | 18.4 |
| Highest temperature | 24.7 |
Calculate the temperature change.
Explain what the temperature change shows about energy transfer and the relative energy of the products and reactants.
85 exam-style questions on AQA GCSE Chemistry 5.1 Exothermic and endothermic reactions, covering 5.1.1 Energy transfer during exothermic and endothermic reactions, 5.1.2 Reaction profiles, and 5.1.3 The energy change of reactions. Each one has a worked solution and a mark scheme showing where the marks go.
