The variations in the partial pressures of gaseous molecules produced by the decomposition of C6H6 in a low pressure DC glow discharge in N2/C6H6 and Ar/C6H6 mixtures are measured by the mass spectrometry. Also, rate equations for the partial pressure variations, which consider possible reaction among the gaseous molecules in the low pressure DC glow discharge, with the electrical energy-input, are proposed, and rate constants are determined by fitting the calculated partial pressure variations to the measured partial pressure variations. The rate constants deduced here indicate that C6H6 is mainly decomposed into an intermediate, which is regarded as a fragment of C6H6, the intermediate is decomposed into mainly C2H2, and then C2H2 is converted into H2 and HCN (only in N2/C6H6).
