CAR PHASE REACTIONS IN SILENT ELECTRIC-DISCHARGES .3. INVESTIGATION OF CHEMICAL-REACTIONS INVOLVING ELECTRON-MOLECULE COLLISIONS IN VARIOUSMIXTURES OF O-2 WITH AR, N-2 OR CO

Electron-molecule collisions play a significant role in chemical trans formations in a silent electric discharge. The reaction rate coefficie nts of electron-molecule collisions in various gaseous mixtures of Ar, N-2 or CO with O-2 have been investigated. These coefficients can be determined experimentally and calculated theoretically. The measured v alues are in good agreement with those calculated by theoretical metho ds. The reaction rate coefficients of electron-O-2, molecule collision s increase with decrease of the amount of O-2 in Ar/O-2 mixtures, but decrease with decrease of the amount of O-2 in N-2/O-2 or CO/O-2 mixtu res.
