For the reaction:

2 H2 + 2 NO → N2 + 2 H2O

the observed rate expression, under some conditions, is:

rate = k[H2][NO]

Which of the following mechanisms are consistent with these data?

Select all that are True.
step 1   2 NO → N2O2     (slow)
     step 2   N2O2 + H2 → N2O + H2O     (fast)
     step 3   N2O + H2 → N2 + H2O     (fast)


step 1   NO + NO ⇌ N2O2     (fast)
     step 2   N2O2 + H2 → N2 + H2O + O     (slow)
     step 3   O + H2 → H2O     (fast)


step 1   2 NO ⇌ N2O2     (fast)
     step 2   N2O2 + H2 → N2O + H2O     (slow)
     step 3   N2O + H2 → N2 + H2O     (fast)


step 1   H2 + 2 NO → N2O + H2O     (slow)
     step 2   N2O + H2 → N2 + H2O     (fast)
