The decomposition of nitramide, O, NNH,, in water has the chemical equation and rate law
[0,NNH,]
[H*]
О,NNH, (aq) —
N,O(g) + H,О(1)
rate =
A proposed mechanism for this reaction is
k1
1. O,NNH, (aq)
= 0,NNH (aq) + H* (aq) (fast equilibrium)
k-1
k2
2. O,NNH (aq) → N,0(g) + OH¯(aq) (slow)
k3
3. H (аq) + ОН (аq) — Н,О() (fast)
H,O(1) (fast)
>
What is the relationship between the observed value of k and the rate constants for the individual steps of the mechanism?
Answer Bank
k =
k1
k-1
k3
k2
