The kinetics of reaction between oxygen atoms and sulfur dioxide: an investigation by electron spin resonance spectrometry

摘要: The kinetics of disappearance oxygen atoms in the presence sulfur dioxide at 299 +- 2/sup 0/K and total pressure 0.7 to 3 torr have been determined using e.s.r. spectrometry measure concentration atoms. most direct interpretation data leads mean values k = (2.7 0.5) x 10/sup 15/ cm/sup 6/ mole/sup -2/ sec/sup -1/, (2.4 0.15) (10 4) -1/ respectively for rate constants reactions O + SO/sub 2/ O/sub ..-->.. 3/ 2/, Ar Ar, 2/.
