The Importance Of Chemical Kinetics

Chemical kinetics studies and determines the rate or speed at which chemical or physical processes occur (Oliver,n.d.)(Jircitano, n.d.). The rate of reaction is the speed at which the reactant in a reaction transforms into products or the change in concentration of a chemical species over the time taken for that change to occur (Oliver,n.d.)(Jircitano, n.d.)(Mack, n.d.)(Blackburn,n.d.). Chemical reactions occur at many different rates and in aqueous or equilibrium systems this rate is dependent on the variables such as the reactivity of reagents, initial concentrations, temperature induced fluctuations and any means of catalysis. (Oliver,n.d.)(Jircitano, n.d.)(Blackburn,n.d.). In order to measure rate the change in concentration in a particular reaction must be determined as well as the time of which this occurred. However studying the concentration at any time during a reaction is problematic since the reaction must be stopped and a sample must be removed both which negatively affect accuracy. One class of reactions that enables the change in concentration to be observed at a particular time is clock reactions. Ina clock reaction an initial induction phase precedes a significant change in concentration of a particular species. (Preece, King, Billingham, 1999). The rapid increase in concentration results in significant effects such as dramatic color change. There are two types of clock reaction: 1. Induction where as small concentration grows till it results in
