Abstract

Relative rate techniques were used to study the kinetics of the reaction of OH radicals with acetylene at 296 K in 25–8000 Torr of air, N~2~/O~2~, or O~2~ diluent. Results obtained at total pressures of 25–750 Torr were in good agreement with the literature data. At pressures >3000 Torr, our results were substantially (∼35%) lower than that reported previously. The kinetic data obtained over the pressure range 25–8000 Torr are well described (within 15%) by the Troe expression using k~o~ = (2.92 ± 0.55) × 10^−30^ cm^6^ molecule^−2^ s^−1^, k~∞~ = (9.69 ± 0.30) × 10^−13^ cm^3^ molecule^−1^ s^−1^, and F~c~ = 0.60. At 760 Torr total pressure, this expression gives k = 8.49 × 10^−13^ cm molecule^−1^ s^−1^. © 2003 Wiley Periodicals, Inc. Int J Chem Kinet 35: 191–197, 2003
