when a reaction mechanism is given:

 rate law only involves the reactants
▪ the coefficients of the reactants in the step are the order of the reaction with respect to that reactant


rate 1 =

(1) O2NNH2(aq) k-1k1 O2NNH-(aq)+H+(aq)      (fast equilibrium)


Reactant → O2NNH2 only:

rate 1 = k1[O2NNH2]


rate-1 =

Reactant → O2NNH- and H+:

rate -1 = k-1[O2NNH-][H+]

Problem Details

The decomposition of nitramide, O2NNH2, in water has the following chemical equation and rate law. 

O2NNH2(aq) → N2O (g) + H2O(l) 

rate = [O2NNH2]/[H]     

            

A proposed mechanism for this reaction is.

(1) O2NNH2(aq) k-1k1 O2NNH-(aq)+H+(aq)      (fast equilibrium)(2) O2NNH-(aq)k2 N2O(aq)+OH-(aq)       (slow)(3) H+(aq)+OH-(aq)k3H2O(l)        (fast)


Determine the rate laws for each elementary step:

rate 1 =

rate-1 =

rate 2 =

rate 3 =
