1. How Fast ? LO: Define what is meant by ‘rate of reaction’ (D) Explain how you could find the rate of a reaction (C) Investigate the rate of reaction (B) Plan how you can find out the rate of a reaction (A) Starter FAST SLOW

2. RATE OF REACTION = how fast a chemical reaction is happening Write down your own examples of a FAST and a SLOW chemical reaction.

3. Suggest How can we measure the rate of a reaction. 2 minutes thinking in silence. Discuss with someone else for 2 minutes. Class Discussion.

4. Rate of reaction = amount of reactant used time Rate of reaction = amount of product made time

5. The method for measuring the rate of a reaction will depend on the reaction. Change in mass Measure the volume of gas given off Measure how long for the reaction to change colour Measure how long for the reaction to go cloudy

6. Practical Time (mins) Volume (cm 3 )

7. Draw a diagram of the practical Write a method for the practical Draw a graph of the results

8. Mass (g) Time (s)
