By the end you’ll be able to

define the rate of a chemical reaction in terms of the speed of disappearance of reactants or appearance of products
measure rate of reaction from practical observations such as gas volume produced, mass lost, precipitate formation or colour change
calculate mean rate from experimental data using change divided by time, with units appropriate to the quantity measured

explain reactions in terms of collision theory, including that particles must collide and that only some collisions are successful

explain successful collisions in terms of particles colliding with sufficient energy and, where specified, the correct orientation
