Resumo
Using atomic resonance absorption spectroscopy, we measure the temporal profiles of Cl atom concentration at interaction with acetylene behind shock waves. We used CCl4 thermal decay as the chlorine atom source. We used a 30 ppm of CCl4 and 300 ppm of C2H2 in argon mixture for the experiments, at 1400–2300 K and pressures of about 2 bar. For experimental results, we determine the rate constant of the chlorine atom consumption in the Cl + C2H2 = C2H + HCl reaction. The experimental data show essentially lower activation energy than the results of the theoretical calculations performed earlier, possibly due to the acetylene molecule vibrational energy contributing to overcoming the reaction barrier.
