Figure 5.

Dependence of the N₃O formation rate constant (k_app) on the solution pH (adjusted with NaOH at pH ≥ 12 and 0.1 M borate at pH 10). (Inset) pH independence of the slow step rate constant (k_slow) for N₃O formation in buffered solutions. Both solid lines correspond to Eq. 17 with a = 1.1 × 10⁴ s⁻¹ and b = 5.3 × 10⁴ M⁻¹⋅s⁻¹. All data are for NO-saturated solutions.
