Abstract : The rate of dissociation of nitrogen trifluoride in excess argon has been determined by measuring the rate of formation of NF2 in the temperature range 1050-1390K using a shock tube-spectrophotometric technique. In the range of 2.7-6.0 atm total pressure the reaction was found to be first order in both NF3 and Ar concentrations. The reaction may be represented by NF3 + M yields NF2 + F + M and for small conversions, other reactions are shown to be unimportant. The temperature dependence of the bimolecular rate constants is described. (Modified author abstract)
