Please look at the link to rates of reaction and make sure you understand the following: The collision theory, factors that affect the rate of reaction [temperature, concentration, surface area, catalysts and pressure (for gaseous systems)]. In addition you should be able to sketch enthalpy level diagrams showing the activation energy for exothermic and endothermic reactions. You should also be able to sketch the Maxwell-Boltzmann distribution curve for two different temperatures and be able it to use it to explain how the use of catalyst and increasing the temperature causes an increase in the rate of reaction.
Chem guide rates link Rates of reaction
You also need to think of an experiment that you can investigate a factor that you think will affect the rate. you need to think about all the variables and how you will measure the rate. Please look at the link to practical work to remind yourself of the criteria. This could possibly be used for all three skill areas.
