Description
Having learnt how to measure rates of reaction and interpret rate graphs, we now discuss the five main factors that affect the rate of a reaction: temperature, concentration, pressure, surface area and catalysts. In the second half of the video, we also look at the requirements for the core practical on this topic: investigating how changes in concentration affect the rates of reactions, with specific reference to a method involving a change in colour.
