Nitrogen Dioxide Reacts with Carbon Monoxide to Produce Nitrogen Monoxide

question 39

Multiple Choice

Nitrogen dioxide reacts with carbon monoxide to produce nitrogen monoxide and carbon dioxide. NO₂(g) + CO(g) → NO(g) + CO₂(g)
A proposed mechanism for this reaction is
2 NO₂(g) NO₃(g) + NO(g)
(fast,equilibrium)
NO₃(g) + CO(g) → NO₂(g) + CO₂(g)
(slow)
What is a rate law that is consistent with the proposed mechanism?

• A) rate = k[NO₂]²[CO] [NO]^-1
• B) rate = k[NO₂]²[CO]
• C) rate = k[NO₂][CO]
• D) rate = k[NO₃][CO]
• E) rate = k[NO₂]²
