摘要：

The rate of thermal decomposition of sulfur dioxide dilute in argon has been measured in a shock tube, using IR emission from the v3 band to monitor SO2. These results yielded a rate coefficient k = 8(±2)×1015 exp(-108000/RT) cm3 mole -1 sec-1 for the reaction SO2+M→SO+O+M in the temperature range 2800 to 3880°K and the total concentration range 8 × 10-6 to 3.4 × 10-5 mole/cc. The measured rate coefficient agrees well with the results of Just and Kiefer, determined respectively from O-atom formation rate observations and densitometric measurements, and the combined data yield a common rate coefficient between 2500 and 5200°K. © 1979 American Institute of Physics.
