In the Atmosphere under the various physical and chemical condition different chemical reactions occur and there are a number of air pollutants which are generated by photochemical reaction by absorbing solar energy. Therefor various testing simulation was done as foundation work to develop the numerical model for the prediction of concentration of air pollutants. It was shown change of major air pollutants concentration in according to variation of photodissociation speed constant, K_1 and initial condition of air pollutants concentration which plays major role in photochemical reaction.
The photochemical reaction model which was used in this study is found to be useful for understanding relationship among the concentration of reacting air pollutants and the prediction of concentration of air pollutants in urban atmosphere
