Question:- Example of a photochemical reaction.
Answer:-1) Photosynthesis where CO2 and H2O gets converted to Glucose and O2 in the presence of light and with the help of chlorophyll in the chloroplasts which help to capture the light energy..
2) Synthesis of Vitamin D under our skin when exposed to sunlight is also an example of photochemical reaction.
3) In chemistry too there are several photochemical reactions like Halogenation of Alkanes takes place in the presence of light.

HLO MATE HERE IS UR ANSWER.
⭐. The decomposition reaction which occur in the presence of sunlight are called "photochemical reactions".
❤. EXPERIMENT ❤
⭐. Take some quantity of silver bromide on a water glass.
⭐. It is yellow coloured powerd.
⭐. Place the watch glass in sunlight for some time.
⭐. Now observe the colour of silver bromide .
⭐. Silver bromide decomposes to silver and bromine in sunlight.
⭐. Light yellow coloured silver bromide turns ti grey due to sunlight.
⭐. The reaction 2AgBr-----------> 2Ag + Br2.
