Rates of reaction flashcards

This activity is an introduction to what is meant by rate of reaction and how rates of reaction are measured. It also helps students to recognise the equation for mean rate of reaction.

The resource focuses on ways of measuring the rate (decreasing mass on a balance, increasing gas volume in a gas syringe, turbidity of precipitate). The flashcards can be used in a variety of ways:

• Give students the cards without answers so that they can write their own responses. They can check them against the cards with answers.
• Use the completed cards in pairs to check each other’s knowledge and understanding.

This is a useful learning check following a demonstration/practical and after the explanation phase of a lesson. It encourages students to think about new terminology and the differences in how rates can be measured.
