AQA GCSE 9-1 Chemistry Unit 6 The rate and extent of chemical change 6.1 Rate of Reaction

4.6 The rate and extent of chemical change
4.6.1 Rate of reaction
4.6.1.1 Calculating rates of reactions
4.6.1.2 Factors which affect the rates of chemical reactions
4.6.1.3 Collision theory and activation energy
4.6.1.4 Catalysts
Required practical 5: investigate how changes in concentration affect the rates of reactions by a
method involving measuring the volume of a gas produced and a method involving a change in
colour or turbidity.
This should be an investigation involving developing a hypothesis.
