III. THEORETICAL CONSIDERATIONS

3.1 PrinciDles of Chemioal Kinetic~

The discipline of chemical kinetios is the study of the rates of

chemical reaotions and physical prooesses. A related study is the

deduction of the meohanism(s) of the reaction or prooess from the

observed rates. _,~~~~~~._~~Iletios differs from oth!~,"~,!.!lQJ'l!!.^,9f

Ilnetios begins with a knowledge of the reaotants and produots of a

chemical reaction or physioal prooess in the form of a chemical or

physical reaotion equation,

where letters denote chemical or physioal species and k is the empirical

reaction rate constant. From the chemical equation, a differential rate

where brackets denote concentrations and lower case letters represent

the empirical order of the reaction with respect to the oorresponding

reaotion species.

A oommon method of ohemical kinetics methodology is to observe the

reaction in a constant-volume, batch reactor where all reactant
