Abstract

The reaction has been studied in a fast-flow system, using a mass spectrometer to monitor the partial pressures of reactants and products. The ratio of Cl2O to O consumed was 0.8, with excess Cl2O present in a poisoned system at total pressures near 0.25 torr. The following reaction scheme is proposed to account for the observations: (1) O + Cl2O ? 2ClO; (2) O + ClO ? O2 + Cl; (3) Cl + Cl2O ? Cl2 + ClO; (4) Cl + wall ? 1/2Cl2; (5) 2ClO ? Cl2 + O2, where we find that k1 = (8.3 ± 1.4) × 1012 cm3 mol-1 sec-1 and k2 = k1.
