Shock Tube Measurement of the CH3 + C2H6 CH4 + C2H5 Rate Constant.
The journal of physical chemistry. A
The rate constant for the CH3 + C2H6 CH4 + C2H5 reaction was studied behind reflected shock waves at temperatures between 1369 and 1626 K and pressures from 8.6 to 47.4 atm in mixtures of methane, ethane, and argon. Ethylene time histories were measured using laser absorption of radiation from a carbon dioxide gas laser near 10.532 mum. The resulting rate constant data can be represented by the Arrhenius equation k (T) = 3.90 * 1013 exp(-16670 cal/mol/RT) cm3 mol-1 s-1. We believe this is the first study to extend experimental data for this rate constant to temperatures above 1400 K. The overall 2sigma uncertainty of the current data is +18%/-21% resulting primarily from uncertainties associated with the influence of secondary reactions and the fitting of rapidly changing species time histories at the higher temperatures.

Shock Tube Measurement of the C2H4 + H double left right arrow C2H3 + H-2 Rate Constant
JOURNAL OF PHYSICAL CHEMISTRY A

The rate constant for the reaction C2H4+H⇒C2H3+H2 was studied behind reflected shock waves at temperatures between 1619 and 1948 K and pressures near 10 atm in a mixture of C2H4, CH4, H2, and argon. C2H4 time-histories were measured using laser absorption of a CO2 gas laser near 10.53 microns. Experimental mixtures were designed to optimize sensitivity to the title reaction with only weak sensitivity to secondary reactions. Two mechanisms, FFCM1 and ARAMCO v2, are used for data analysis. The well-selected operating conditions and Monte-Carlo Sampling data analysis procedure resulted in mechanism independent reaction rate constant measurements with 2σ uncertainty of +/-35 %. The current data disagree with a broadly used theoretical calculation (Knyazev et al. (1996)), but they are in good consensus with one of the review studies (Baulch et al. (2005)), k=3.9×1022T3.62exp(-5670/T) cm3molecule-1s-1. To the best of our knowledge, this work provides the first high temperature study of C2H4+H⇒C2H3+H2 reaction rate constant with well-defined uncertainty.
