Recently, theoretical analysis and investigations have begun to evaluate that some free radicals are generated by chemical reactions. The free radicals and other products of reactions are often more irritating than their precursors. Especially, the products of ozone/terpene reactions cause greater airway irritation in mice than would be predicted based on the known response of mice to ozone or terpenes. This paper presents an analysis of chemically reactive pollutants in indoor air and describes the development of a cylindrical test chamber that can be used to obtain second order rate constant (k_b) for bi-molecular chemical reaction of ozone and terpene in air phase. Ozone and terpene were introduced into the supply air at a constant concentration in the cylindrical test chamber and the reduction in the ozone and terpene concentrations were measured after they had passed over the distance of cylindrical test chamber. To directly estimate the second order rate constant (k_b) of bi-molecular reaction of ozone and terpene, a theoretical analysis was conducted using a fundamental chemical reaction model based on rate constant.
