SHOCK TUBES STUDY OF THE DISSOCIATION OF CARBON DIOXIDE.
Abstract
The rate of dissociation of carbon dioxide in an excess of argon or nitrogen has been measured in the temperature range 3300K - 5000K. A shock tube was used to heat the gas mixture which contained from 1% to 10% carbon dioxide. It is shown that the decrease in temperature and the increase in density due to the endothermic dissociation must be considered to obtain reliable results. The total concentration of the gas mixture was varied from 0.000011 to 0.00000486 moles/cc. The rate constants were determined to be k1,A = (7.11 x 10 to the 11th power) T to the 1/2 power exp(-84,500/RT) cc/mole sec when argon was used as the diluent; and k1,N2 = (5.33 x 10 to the 11th power) T to the 1/2 power exp(-79,600/RT) cc/mole sec when nitrogen was used as the diluent. The probable dissociation mechanism also is discussed. (Author)
