Rate of reaction required practical (Part 1)

In this lesson, students will complete the required practical: Investigate the effect of concentration on the rate of reaction by a method involving measuring the volume of a gas produced. Students will go over the variables to change, measure and control. At the end of the required practical, students will learn how to display data appropriately and how to check reproducibility.
