The gas phase reaction of carbon monoxide with nitrogen dioxide is believed to occur by the following mechanism: step I slow: 2 NO_2 rightarrow NO_3 + NO step 2 fast: NO_3 + CO rightarrow NO_2 + CO_2 What is the equation for the overall reaction? Use the smallest integer coefficients possible. If a box is not needed, leave it blank. Which species acts as a catalyst? Enter formula. If none, leave box blank: Which species acts as a reaction intermediate? Enter formula. If none, leave box blank: Complete the rate law for the overall reaction that is consistent with this mechanism. (Use the form k[A]^m|B|^n..., where '1' is understood (so don't write it) for m, n etc.) Rate =
