Correction -- there is no [H2] in the final equation because the steady
state approximation gives and expression for the [N2O2] concentration
that has [H2] in the denominator, so when you use it in the second step
to find the rate of [N2O] it cancels.
Should be
d[N2O]/dt = k_1 k_2 [NO]^2 / (k_(-1) - k_2)

When I worked number 3 in class the other day I had mistakingly pulled
my solution from an older worksheet. If you use the steady state
equation and the two step mechanism from Worksheet 5 the rate of
appearance of N2O should be
d[N2O]/dt = k_1 k_2 [NO]^2 [H2] / (k_(-1) - k_2)
