The C6H6 decomposition at atmospheric pressure is investigated using a barrier discharge in Ar at less than 4% O2. C6H6 in the presence of O2 in Ar is decomposed to CO, CO2, H2O, and HCOOH. Concentrations of these products are shown versus the concentration of C6H6 decomposed with different amounts of electrical inputs, flow rates, and initial C6H6 concentrations. At 4% O2, concentrations of CO and HCOOH are proportional to the concentration of C6H6 decomposed. The concentrations of CO2 and H2O increase with increasing concentration of C6H6 decomposed at flow rate of 1000mL/min. However, at flow rates of 200mL/min and 500mL/min, the concentrations of CO2 and H2O do not increase with increasing concentration of C6H6 decomposed. As results of considering the dependence of the concentration of products and a simple calculation for chemical reactions, the concentration of O atoms produced by the discharge determines not the concentration of C6H6 decomposed but the concentrations of products.
