Photochemical reaction:

A Photochemical reaction is a reaction which takes place when a chemical process absorbs light energy as its energy source. The example is photosynthesis.

In photosynthesis, light energy is captured by the chlorophyll present in the thylakoids of the chloroplast in order to produce photons to facilitate the conversion of water and carbon dioxide into sucrose or starch.

The photons from the light energy split water and enable ATP production that drives the entire process.

For example
2AgCl ---------> 2Ag + Cl in the presence of sunlight
The silver Chloride turns grey

Chemical reactions which take place in the presence of light are called photo chemical reactions. For example - 6CO2 + 6H2O = C6H12O6 + 6O2
