Photochemical Smog NO₂ Data Analysis
The table provides data on the concentration of nitrogen dioxide (NO₂) during the formation of photochemical smog. From 11:00 A.M. to 4:00 P.M., the rate of NO₂ formation is approximately 7 ppm per hour. All of the following statements are true regarding this period EXCEPT:
| Time (hr) | NO₂ Concentration (ppm) |
|---|---|
| 11 | 15 |
| 16 | 50 |
A
Multiplying the rate (7 ppm/hr) by 5 hours gives a total increase of 35 ppm.
B
The total increase in NO2 over this 5-hour period is 42 ppm.
C
The rate of increase is 7 ppm per hour.
D
A constant rate of 7 ppm/hr indicates a linear accumulation of NO2 over time.
