What are the chemicals in photochemical smog?

What are the chemicals in photochemical smog?

The major undesirable components of photochemical smog are nitrogen dioxide (NO2), ozone (O3), PAN (peroxyacetylnitrate), and chemical compounds that contain the –CHO group (aldehydes). PAN and aldehydes can cause eye irritation and plant damage if their concentrations are sufficiently high.

What is the chemical reaction of industrial smog?

Photochemical smog is a type of air pollution due to the reaction of solar radiation with airborne pollutant mixtures of nitrogen oxides (NOx) and volatile organic compounds (hydrocarbons). Smog is a byproduct of modern industrialization.

What is the composition of photochemical smog *?

The common components of photochemical smog are ozone, nitric oxide, acrolein, formaldehyde and peroxyacetyl nitrate (PAN).

What is chemical formula for ozone?

O₃
Ozone/Formula

What is the formula for the oxide of nitrogen that initiates the formation of photochemical smog?

The formula for the oxide of nitrogen that initiates the formation of photochemical smog is N2 + O2 ⟶ 2NO N 2 + O 2 ⟶ 2 N O .

Which gas is formed in photochemical smog?

nitrogen dioxide
Among the pollutants involved in photochemical smogs are ozone, nitrogen dioxide and peroxyacyl nitrate (PAN). The nitrogen dioxide, and other oxides of nitrogen, are primary pollutants produced by dissociation in combustion reactions, and both ‘prompt’ and ‘thermal’ NOx can be involved in the reactions.

Is ozone a component of photochemical smog?

A key component of photochemical smog, ozone is formed by a complex reaction between nitrogen dioxide and hydrocarbons in the presence of sunlight.

What is the main oxidant in photochemical smog?

ozone
The photochemical oxidants are secondary air pollutants formed by the action of sunlight on nitrogen oxides and reactive hydrocarbons, their precursors. The most important phytotoxic components produced by these atmospheric photochemical reactions are ozone and peroxyacetyl nitrate.
