The rate law for the reaction 2H2(g) + 2NO(g) → N2(g) + 2H2O(g) is given by rate = k [H2] [NO]2.
The reaction occurs in the following two steps :
(i) H2(g) + 2NO(g) → N2O(g) + H2O(g)
(ii) N2O(g) + H2(g) → N2(g) + H2O(g)
What is the role of N2O in the mechanism? What is the molecularity of each of the elementary steps?
