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) Nitrogen dioxide reacts with carbon monoxide to produce nitrogen monoxide and carbon dioxide. NO<sub>2</sub>(g) + CO(g) → NO(g) + CO<sub>2</sub>(g)  A proposed mechanism for this reaction is 2 NO<sub>2</sub>(g)    NO<sub>3</sub>(g) + NO(g)  (fast,equilibrium)  NO<sub>3</sub>(g) + CO(g) → NO<sub>2</sub>(g) + CO<sub>2</sub>(g)  (slow)  What is a rate law that is consistent with the proposed mechanism? A)  rate = k[NO<sub>2</sub>]<sup>2</sup>[CO] [NO]<sup>-1</sup> B)  rate = k[NO<sub>2</sub>]<sup>2</sup>[CO] C)  rate = k[NO<sub>2</sub>][CO] D)  rate = k[NO<sub>3</sub>][CO] E)  rate = k[NO<sub>2</sub>]<sup>2</sup> 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?
