10. For the reaction between nitric oxide and hydrogen,
2NO(g) + H2(g) →N2O(g) + H2O(g)
may proceed via the following mechanism:
1. 2NO \(\xrightarrow{k_1}\) \(\xleftarrow{k_{-1}}\) N2O2
2. N2O2 + H2 \(\xrightarrow{k_2}\) N2O + H2O
Write the rate law for this reaction by using the steady-state approximation if step 2 is the rate-determining step in this mechanism. (10 %)
