A Possible Reaction Mechanism for the Reaction of Nitrogen Dioxide

question 26

Multiple Choice

A possible reaction mechanism for the reaction of nitrogen dioxide with carbon monoxide is
$\begin{array}{l}2 \mathrm{NO}_{2}(g) \rightarrow \mathrm{NO}_{3}(g) +\mathrm{NO}(g) &(slow) \\\mathrm{NO}_{3}(g) +\mathrm{CO}(g) \rightarrow \mathrm{NO}_{2}(g) +\mathrm{CO}_{2}(g) &(fast) \end{array}$

What is the overall reaction and the most probable rate law for the reaction?

• A) NO₂(g)+ CO(g)? NO(g)+ CO₂(g);rate = k[NO₂]
• B) NO₂(g)+ CO(g)? NO(g)+ CO₂(g);rate = k[NO₂]²
• C) NO₂(g)+ CO(g)? NO(g)+ CO₂(g);rate = k[NO₃]×[CO]
• D) 2NO₂(g)+ CO(g)? NO(g)+ CO₂(g);rate = k[NO₂]×[ NO₃]×[CO]
• E) 2NO₂(g)+ CO(g)? NO(g)+ CO₂(g);rate = k[NO₃]×[CO]
