Enter a number 1 points Save Answer Question 5 Two mechanisms have been proposed for the reaction of nitrogen monoxide with ozone: NO + O3 → NO2 + 02. The known rate law for this reaction is rate-k[NO][03]. Select all of the correct statements below Mechanism I (one step): NO +03 NO2+ 02 Mechanism!! (two step): Step 1-O3 → O2 + O (slow step); Step 2-NO + O → NO2 (fast step) Mechanism correct. The reaction is bimolecular O O is an intermediate. The reaction is unimolecular](https://media.cheggcdn.com/media%2F347%2F3476a00b-e843-44bf-ae5d-e89fc41af778%2Fimage)
Identify the intermediate in the following mechanism: Step 1: NO_2 + NO_2 rightarrow NO_3 + NO Step 2: NO_3 + CO rightarrow NO_2 + CO_2 NO_2 NO_3 NO CO CO_2 What is the order with respect to NO_2 in the elementary step NO_2 + NO_2 rightarrow NO_3 + NO? Enter a number. Two mechanisms have been proposed for the reaction of nitrogen monoxide with ozone: NO + O_3 rightarrow NO_2 + O_2. The known rate law for this reaction is rate =k[NO][O_3]. Select all of the correct statements below. Mechanism I (one step): NO + O_3 rightarrow NO_2 + O_2 Mechanism II (two step): Step 1 – O_3 rightarrow O_2 + O (slow step): Step 2 – NO + O rightarrow NO_2 (fast step) Mechanism I is correct. The reaction is bimolecular O is an intermediate. The reaction is unimolecular
Expert Answer
Answer
1. NO3 is the intermediate ( It can be explained in terms of the initiator for the second step)
There is no direct involvement of NO3 its just connect between step A and Step B
| 2.
NO2 + CO rate = k[NO2]2 Thus the order of reaction with respect to NO2 is 2. 3. Mechanism 1 is correct O is an intermediate The reaction is unimolecular |
NO + CO2 (Overall reaction)
