photochemical oxidation reactions are driven by

Photochemical smog occurs due to the action of sunlight on air pollutants, generating photochemical reactions. The principal constituents of the photochemical smog are gaseous hydrocarbons (leading to ozone formation) and oxides of nitrogen (NO x )..

There are many reactions that are affected by electromagnetic radiations. Chemical reactions, which occur in the presence of visible and ultraviolet light are called photochemical reactions. Photochemical reactions occur only when photons ..

When pollutants like hydrocarbons and nitrogen oxides combine in the presence of sunlight, smog is formed. This is a mixture of gases and since it is formed by photochemical reactions, it is called the photochemical smog. The word 'smog' is derived from the t..

Morning and evening office hours lead to an increase in vehicular traffic. The emissions of CO, hydrocarbons and oxides of nitrogen increase during these times. These chemicals are also emitted by industries and power plants. NO 2 a good absorber of U.V. ray and visible radiation from t..

Light Phase consists of photochemical reactions which are carried out by two different photo systems, PS-I and PS-II. In the thylakoids, chlorophyll and other molecules are packed into units called photo systems. Each photosystem unit contains from 250 to 400 molecules of pigmen..
