| Abstract: | Mechanism of the dissociation reactions of NO/SO_2/N_2/O_2 gaseous molecules in non- thermal plasma was investigated.Energy distribution function and chemical reaction rate coefficients were calculated through Boltzmann equation analysis and collision theory.The rate coefficients for electron collisions were fitted to Arrhenius form.The relation between chemical reaction rate and electron temperature was presented to judge the importance of each reaction and to predict the process of gaseous chemical reaction. |
