The addition of SiCl3 radicals to ethylene has been reinvestigated using a large conversion method.The amended values are log(k₃/k₅) = -0.17 +/- 0.05 - (0.80 +/- 0.10) kcal mol^-1/2.303 RT and log -5/k₆ (mol cm^-3)> = 3.4 +/- 0.3 - (22.5 +/- 0.7) kcal mol^-1/2.303 RT where the reactions involved are radical-SiCl3 + CH3COCH3 <*> (CH3)2-radical-COSiCl3, radical-SiCl3 + C2H4 <*> radical-CH2CH2SiCl3 and radical-CH2CH2SiCl3 + HSiCl3 <*> C2H5SiCl3 + radical-SiCl3.
