This formative assessment is designed to evaluate students’ understanding of energetics, a core topic in secondary chemistry. Fully compatible with Edexcel IGCSE, AQA, and Cambridge specifications, this resource offers a structured approach to testing key concepts in exothermic and endothermic reactions, energy level diagrams, and enthalpy change calculations.

Key Features

• Thorough coverage of exothermic and endothermic processes, including reaction profiles, bond energy calculations, and the interpretation of energy change data.

• Engaging and varied question types, from recall and definitions to energy level diagram analysis and bond enthalpy calculations.

• Real-world applications, with contexts such as self-heating cans, instant cold packs, and combustion reactions.

• Ideal for classroom assessment, homework, revision, or flipped learning tasks.

Educational Benefits

Reinforces students’ ability to describe, interpret, and calculate energy changes in chemical reactions.

Supports exam preparation by promoting correct use of terminology and calculation methods.

Suitable for mixed-ability classes, with scaffolding and stretch opportunities built in.

Answers for calculations included
