Question

Consider the following three-step reaction pathway.

Step 1: 2NO(g) right facing arrow N2O2(g)
Step 2: N2O2(g) + H2(g) right facing arrow N2O(g) + H2O(g)
Step 3: N2O(g) + H2(g) right facing arrow N2(g) + H2O(g)

Which is the correct list of reaction intermediates from the reaction pathway above?
2NO(g), H2(g), and N2O(g)
N2O2(g) and N2O(g)
N2(g) + H2O(g)
N2O2(g)
