Question

the concentrations of nitric oxide (no) and nitrogen dioxide (no2) and ozone (o3) are generalized for a large city over a 24 - hour period. variations of nitrogen oxides (no and no2) and ozone (o3) over time which of the following most likely explains why ozone concentration peaks between late morning until early afternoon? choose 1 answer: the midday sun provides energy for ozone formation. the moisture in the afternoon dew favors ozone formation. cool morning temperatures favor ozone formation. strong morning winds mix the two nitrogen oxides to form ozone.

Explanation:

Ozone is formed through photochemical reactions. The mid - day sun provides the ultraviolet (UV) radiation needed to drive the reactions that convert nitrogen oxides and volatile organic compounds into ozone. Afternoon dew is not a factor in ozone formation, cool morning temperatures do not favor ozone formation, and strong morning winds mixing nitrogen oxides are not the main cause of the ozone peak.

Answer:

A. The midday sun provides energy for ozone formation.
