it happens in the thylakoids of a chloroplast.
Photochemical reaction: a chemical reaction induced by electromagnetic radiations: ul- traviolet, visible, etc.) Thermal reaction: a chemical reaction induced by increasing the temperature (ex.: thermal dissociation, etc.)
photochemical smog is formed by a complex process . photochemical smog irritates breathing passages, plants, and damage rubber,plants,and some plastics
Photolytic Reaction
Because it depends upon light.
A primary photochemical reaction is the immediate consequence of the absorption of light. Subsequent chemical changes are called secondary processes. http://edelsteincenter.files.wordpress.com/2010/07/photochemistry.pdf
In photochemical reaction we have photons that passed to the surface starting photochemical reaction - producing some electrons. quantum yield=produced electrons/passed photons.

The splitting of water
ozone
The reaction between methane and bromine is a photochemical reaction. Refer to the related link below.
There are two major types of smog: photochemical and industrial smog. Photochemical smog is created through a reaction by which air pollutants are struck by sunlight, and form particulate matter and tropospheric ozone. The air pollutants that are most responsible for this type of smog are nitrogen oxides (NOx) and volatile organic compounds (VOCs). Photochemical is especially a problem in areas with many cars, coal-burning power plants, and the right weather conditions. Los Angeles, CA is a city that often has to deal with photochemical smog.
