$: \implies \rm \: 2AgCl \xrightarrow{sunlight}2Ag + Cl_2$

$: \implies \rm \: 2AgBr \xrightarrow{sunlight}2Ag + Br_2$

This reaction is used in black and white photography

More information

Its type of decomposition reaction

=> The reaction in which single substance broken down to a form two or more substance is called decomposition reaction

The decomposition is mainly three types

=> above reaction is come in photo decomposition reaction

Photo decomposition reaction

The decomposition reaction in which take place in the presence of sunlight is called photo decomposition reaction

Take a look on characteristics of chemical reactions

i) Evolution of gas

ii) change in color

iii) change in state

iv) Change in temperature
