Rate constant for the reaction Cl + HO2NO2 → products

The total rate constant for the reaction of Cl atoms with HO₂NO₂ was found to be less than 1.0 × 10^?13 cm³ s^?1 at 296 K by the discharge flow/resonance fluorescence technique. The reaction was also studied by the discharge flow/mass spectrometric technique. k_1a + k_1b was measured to be (3.4 ± 1.4) × 10^?14 cm³ s^?1 at 296 K. The reaction is too slow to be of any importance in stratospheric chemistry.
