THE CATALYTIC DECOMPOSITION OF NITROUS OXIDE AND THE THERMAL DECOMPOSITION OF NITROGEN DIOXIDE
Abstract
The reaction between atomic oxygen and nitrous oxide has been studied at temperatures ranging from 1500K to 2100K. To determine the amount of atomic oxygen released in the thermal decomposition of nitrogen dioxide it was necessary to study this decomposition in detail. This study was conducted also at temperatures ranging from 1500K to 2000K and over a wide range of concentrations and pressures. The reaction rates obtained for the various steps in the decomposition of nitrogen dioxide are in general agreement with those obtained by other investigators. The reaction of nitrous oxide in the presence of nitrogen dioxide with argon as the diluent was studied to determine if the oxygen released in the decomposition of nitrogen dioxide would accelerate the decomposition of nitrous oxide. No noticable acceleration was observed. Many experiments were conducted with a nitrous oxide mole fraction of 0.02 and ozone mole fractions varying between 0.005 and 0.06. In these experiments the diluent was molecular oxygen. The presence of atomic oxygen definitely produced an increase in the rate of decomposition of nitrous oxide. It is found that the reaction between atomic oxygen and nitrous oxide is pressure dependent. It is shown that the different rate constants obtained by other investigators may be reasonably explained on the basis of a pressure dependent step in the reaction mechanism.
