摘要: The pyrolysis of tagged ethyl iodide has been studied in the presence radical scavenger toluene a flow system. rate constants for formation C2H4(kD), C2H6(kS), and bibenzyl have determined as function contact time, pressure (2–18 mm Hg), C2H5I PE(0.6–40×10−3 Hg) at 774°K. It is concluded that kD≈k1 kS≈k2 low kiPE, where C2H5I→ lim k1C2H4+HI,C2H5I→ k2C2H5+I. first reaction appears to be order 14 Hg with high‐pressure Arrhenius constant k1∞ 1.27×1014 exp (−52.8×103/RT) sec−1. second not any pressure, but by extrapolation k2∞ was estimated 4.5×1013 (−50×103/RT) sec−1.The RRKM theory used fit dependence k1 k2 approximation same degrees freedom are active energized molecule A* both reactions. disagreement between experiment could result fewer rotational free...
