These elementary steps are proposed for a mechanism:
1) 2NO(g) → N2O2(g)
2) 2H2(g) → 4H(g)
3) N2O2(g) + H(g) → N2O(g) + HO(g)
4) 2HO(g) + 2H(g) → 2H2O(g)
5) H(g) + N2O(g) → HO(g) + N2(g)
a) Write the rate law for the first step.
b) Determine the molecularity ofthe third step.
c) Write the balanced equationfor the overall reaction.
