Carbon monoxide and nitrogen dioxide react to form carbon dioxide and nitrogen monoxide according to the following equation.

\[{\text{CO(g)}} + {\text{N}}{{\text{O}}_2}{\text{(g)}} \to {\text{C}}{{\text{O}}_2}{\text{(g)}} + {\text{NO(g)}}\]

The reaction occurs in a series of steps. The equation for the rate-determining step is given below.

\({\text{2N}}{{\text{O}}_2}{\text{(g)}} \to {\text{N}}{{\text{O}}_3}{\text{(g)}} + {\text{NO(g)}}\)

What is the rate expression for this reaction?

A.     rate \( = k{\text{[CO(g)][N}}{{\text{O}}_2}{\text{(g)]}}\)

B.     rate \( = k{{\text{[N}}{{\text{O}}_2}{\text{(g)]}}^2}\)

C.     rate \( = k{\text{[N}}{{\text{O}}_3}{\text{(g)][NO(g)]}}\)

D.     rate \( = k{\text{[C}}{{\text{O}}_2}{\text{(g)][NO(g)]}}\)

B
