Kinetic studies not only help us to determine
the speed or rate of a chemical reaction but also describe the
conditions by which the reaction rates can be altered The factors
such as concentration, temperature, pressure and catalyst affect the
rate of a reaction At the macroscopic level, we are interested in
amounts reacted or formed and the rates of their consumption or
formation At the molecular level, the reaction mechanisms involving
orientation and energy of molecules undergoing collisions,
are discussed
