Understanding rates of reaction and collision theory

This Venn diagram activity is ideal for diagnosing student misconceptions and helping them gain a really good understanding of collision theory. The statements that need placing have been chosen to prompt debate and discussion and it makes a great whole class activity. Although it was written for keystage 4 students it is also useful to use with keystage 5 students at the start of the topic. A second sheet gives the answers.

There's a follow up worksheet to consolidate important concepts and a further colour in sheet exploring why chemists want to control reaction rates.
