What are the two main components that lead to the production of photochemical smog?

What are the two main components that lead to the production of photochemical smog?

Smog (a.k.a. “photochemical smog”) can be formed just from nitrogen oxides and sunlight—without presence of VOC. This smog is chiefly nitrogen oxides (NOx) and ozone (O3). Smog cannot be formed from just VOCs and sunlight; oxides of nitrogen and an oxidizer (ozone) are required in the chemical reactions.

Which is not present in photochemical smog?

Some of the common nitrogenous compounds are NOX, PAN of which PAN is peroxyacetyl nitrate which is a component of the photochemical smog. But the CFC or chlorofluorocarbon is not a component of the smog as it takes part in the depletion of the ozone layer.

Which of the following components must be present in the atmosphere to create photochemical smog?

Photochemical smog is produced when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere. Nitrogen oxides come from car exhaust, coal power plants, and factory emissions. VOCs are released from gasoline, paints, and many cleaning solvents.

Which of the following is the major photochemical smog?

9. The major photochemical smog is________. Answer: (b) Chlorofluorocarbon.

Is CFC present in photochemical smog?

It is not a component of photochemical smog. while other given compounds are the main components of photochemical smog. Among the given chlorofluorocarbons are the compounds that are responsible for ozone depletion which degrades ozone into molecular oxygen. It is not a component of photochemical smog.

Which gas is commonly found in smog quizlet?

Nitrogen oxide (NO) and nitrogen dioxide (NO2) collectively. These gases play a role in photochemical smog and can irritate the eyes, nose, throat, and lungs; aggravate asthma and bronchitis; and increase susceptibility to respiratory infections by impairing the immune system.

What is produced during formation of photochemical smog?

Notes: During the photochemical smog NO and O3 both are produced but major production is of nitrogen oxide (NO) and NO2. The components of automobile exhaust are particularly important in the formation of atmospheric ozone and are the primary contributors to Los Angeles smog.
