INTRODUCTION Chemical kinetics‚ which can also be explained as reaction kinetics‚ studies the rates of chemical processes and reactions. A lot of this has to do with the speed at which a chemical reaction occurs for instance the rate at which reactants and products appear and disappear. In this case chemical kinetics goes further in depth to understand what conditions affect the rate of a given reaction. This is important because it allows scientists to determine what type of reaction can occur
