![When fuels are burned in the air, such as in an automobile engines, some of the nitrogen in the air
oxidized to form nitrogen oxide gases such as NO and NO2 (known collectively as NO,). The U.S.
Environmental Protection Agency (EPA) sets standards for air quality of several pollutants, including
NO2. According to the EPA, NO2 levels in U.S. cities are not to exceed a yearly average of 53 ppb (parts
per billion) or a 1-hour average of 100 ppb.
Another pollutant associated with automobile exhaust is ozone (O3). The EPA standard for ozone is an
8-hour average of 70 ppb. Breathing air with elevated levels of NO2 or O3 can cause asthma and other
respiratory problems.
The graph below shows the average concentration of NO2 and O3 gases in units of ppb by volume (ppbv)
over seven days in a large city. Study the graph and answer the following questions:

![Q:1 What type of relationship exists between NO2 and O3 between March 14 and March 16?
Q2: Calculate the number of moles of NO2 in 1.00 m³ produced on March 14. Assume an average
temperature of 25.0°C and a pressure of 1.00 atm. Note that the number of moles of NO2 produced is
the difference between the existing amount at the start of the day and the peak amount.
Q3: Calculate the number of moles of O3 in 1.00 m³ produced on March 14. Assume an average
temperature of 25.0°C and a pressure of 1.00 atm. Note that the number of moles of NO2 produced is
the difference between the existing amount at the start of the day and the peak amount.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbf0bf122-634a-44fa-91b8-c1e8a674ef1d%2Fc58d48a5-dbac-4d6f-937c-cfb1e31d8bf7%2Frbx335_processed.png&w=3840&q=75)
