HNO + O2 -> HO2 + NO

SOURCE:

The only experimental value is a maximum reported by Bryukov et al. (1992) and (1993) at 300K. We assumed this value and estimated the A-factor. This result is larger than the values proposed by Dean and Bozzelli (1996) and Miller and Bowman (1991). Comparison with the analogous RH+O2 reaction suggests that a large barrier is not expected.
