Question

(a)   (i) Determine the order for each of the reactants, NO and H2, from the data given in the image below and show your reasoning.

       (ii) Write the overall rate law for the reaction.

 

(b)   The following sequence of elementary steps is a proposed mechanism for the reaction.

         I.     NO + NO ↔ N2O2

        II.     N2O2 + H2 → H2O + N2O

      III.     N2O + H2 → N2 + H2O

       Based on the data presented, which of the above is the rate-determining step? Show that the mechanism is consistent with

(i)    the observed rate law for the reaction, and

(ii)  the overall stoichiometry of the reaction.

 
Note: Please briefly explain the answer above.
2 NO(g) +2 H2(g) → N2(g) + 2 H2O(g) Experiments were conducted to study the rate of the reaction represented by the equation above.
