Question
The decomposition of nitramide, 0,NNH,, in water has the chemical equation and rate law
[0,NNH,]
[H*]
rate = k
0,NNH, (aq) → N,0(g) + H,O(1)
A proposed mechanism for this reaction is
k1
1. 0,NNH,(aq)
O,NNH¯(aq) + H*(aq) (fast equilibrium)
k-1
k2
2. Ο,ΝΝΗ (aq)
N,0(g) + OH¯(aq)
(slow)
k3
3. H*(aq) + OH¯(aq) → 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
