This formative assessment resource is designed to evaluate students’ understanding of rates of chemical reactions, a fundamental topic in secondary chemistry. Fully aligned with Edexcel IGCSE, AQA, and Cambridge specifications, this activity helps teachers assess knowledge of key concepts and students’ ability to apply them in real-world and experimental contexts.

Key Features

• Comprehensive coverage of factors affecting reaction rate, including temperature, concentration, surface area, catalysts, and collision theory.

• Progressively structured questions, from basic recall to extended responses that require interpretation of graphs, analysis of data, and explanation of practical scenarios.

• Incorporates experimental contexts, such as magnesium in acid, sodium thiosulfate and hydrochloric acid, and catalytic decomposition, allowing students to apply theoretical knowledge to practical situations.

• Flexible use as an in-class assessment, homework, flipped learning task, or exam preparation activity.

Educational Benefits

Helps identify misconceptions and gaps in understanding prior to summative testing.

Reinforces key scientific terminology and the ability to describe and explain changes in rate.

Develops data handling and graph interpretation skills through real-life reaction rate investigations.

Differentiated by design, supporting a wide range of learners while offering challenge questions for high achievers.
