The temperature dependence of the rate constant for O + + NO → NO + + O from 23 to 30000 K
The rate constant, k, for the charge transfer reaction O + + NO + +_O, known to be slow at 300 K (8 × 10 −13 cm 3s −1) and to increase with relative kinetic energy (or temperature, T) to 2 × 10 −10 cm 3 s −1 at 30000 K, has been measured down to 23 K. The results show that k also increasesa t low T...

Summary: | The rate constant,
k, for the charge transfer reaction O
+ + NO
+ +_O, known to be slow at 300 K (8 × 10
−13 cm
3s
−1) and to increase with relative kinetic energy (or temperature,
T) to 2 × 10
−10 cm
3 s
−1 at 30000 K, has been measured down to 23 K. The results show that
k also increasesa t low
T (3.2 × 10
−11 cm s
−1 at 23 K) which is interpreted as being due to the formation of a long-lived complex in which electronic state curve crossings occur. |
