The problem is about the decomposition of nitramide (O2NNH2) in water and we’re asked to determine two things:
First, remember that the Elementary steps of the mechanism must result in the overall reaction:
So we add the 3 reaction steps and cancel terms in both reactants and products.
The decomposition of nitramide, O2NNH2, in water has the following chemical equation and rate law:
O2NNH2(aq)→ N2O(g) + H2O(l)
A proposed mechanism for this reaction is:
(1) O2NNH2(aq) ↔ O2NNH(aq) + H(aq) (fast equilibrium)
(2) O2NNH(aq) → N2O(g) + OH(aq) (slow)
(3) H(aq) + OH → H2O(l) (fast)
What is the relationship between the observed value of k and the rate constants for the individual steps of the mechanism?
k = __________
Which symbols go into the numerator or denominator: k-1, k3, k2, k1.
