Consider the following gas phase reaction: CO2 + NO CO + NO2 The overall reaction rate is second-order with respect to CO2. At below 25 C, the overall reaction rate is zero-order with respect to NO. Select the mechanism that is consistent with this rate law.

Group of answer choices

CO2 + CO2 CO3 + CO fast CO3 + NO CO2 + NO2 slow

CO2 + 2NO C + 2NO2 fast C + CO2 2CO slow

CO2 + 2NO CO + 2NO2 fast CO + CO2 2CO + O slow

CO2 + 2NO C + 2NO2 slow C + CO2 2CO fast

CO2 + CO2 CO3 + CO slow CO3 + NO CO2 + NO2 fast
