Abstract
The thermal decomposition of N2O in the presence of added Cl2, Br2, I2, and C2H5I was studied over the temperature range 876 to 1031°K. The catalytic reaction was found to be first order in N2O and in atomic halogen concentration. The rate constants are in the order Cl>Br>I. Activation energies of 33.5, 37, and 38 kcal and pre‐exponential factors of 1.3, 2.0, and 2.8×1014 cc mole−1 sec−1 were found for the Cl, Br, and I reaction. A probable mechanism is discussed and qualitative evidence provided for a high rate constant for the dissociation of Cl2, analogous to reported values for Br2 and I2.Keywords
