Give an example of photo-chemical decomposition reaction in real life.

$\Large\maltese{\underline{\underline{\mathcal{Answer\leadsto}}}}$

Firstly lets understand what is a decomposition reaction →

Decomposition Reaction:- The reaction in which a single reactant breaks down into two or more products is called photo-chemical decomposition.

Energy Required :-

1. Heat
2. Electricity
3. Sunlight

Photo-chemical Decomposition:- The decomposition that occurs in the presence of sunlight is called photo-chemical decomposition.

Examples:-

$\bf{1.\:2AgCl(s)\xrightarrow{Sunlight}2Ag(s)+Cl_2\uparrow\checkmark}$

$\bf{2.\:2AgBr(s)\xrightarrow{h\nu}2Ag(s)+Br_2(l)\checkmark}$

The above reaction is used in black and while photography which is a real life applicable example.
