Practice ProblemATTEMPT

The reaction between ${\text{NO}}_{\text{2}}$ and CO to produce NO and ${\text{CO}}_{\text{2}}$ is thought to occur in two steps:

$Step1:{\text{ NO}}_{\text{2}}{\text{+NO}}_{\text{2}}\stackrel{k_1}{\to }{\text{NO+NO}}_{\text{3}}$

$Step\text{ 2}:{\text{ NO}}_3{\text{+CO}}_{}\stackrel{k_2}{\to }{\text{NO}}_{\text{2}}{\text{+NO}}_2$

The experimental rate law is rate $=k\left[{\text{NO}}_{\text{2}}\right]2$. (a) Write the equation for the overall reaction. (b) Identify the intermediate(s). (c) Identify the rate-determining step.
