A possible mechanism for the reaction
2NO(g) + O₂(g) $\rightarrow$ 2NO₂(g) is: 2NO(g) →N₂O₂(g)
K₁,k₁',fast
N₂O₂(g) + O₂(g) $\rightarrow$ 2NO₂(g)
K₂,slow
Application of the steady-state approximation gives

• A)[N₂O₂] = 0.
• B)k₁[NO]² -k₂[N₂O₂][O₂] = 0.
• C)[N₂O₂] = (k₁/k₂)[NO]².
• D)k₁[NO]² -k₁'[N₂O₂] - k₂[N₂O₂][O₂] = 0.
• E)[N₂O₂] = (k₁/k₁')[NO]².
