Hey mate !!.
Here's is ur answer _______________
________________________________
When white silver chloride is left exposed in the sunlight than, a black metallic colour silver and chlorine gas are produced.
Equation:--. 2AgCl >>> sunlight >> 2Ag+ Cl2
This reaction is , photo decomposition reaction.
Dear:) hope its helps ☺

Hey there!
Decomposition Reaction: It is a reaction that takes place by the decomposition of a substance through various sources of energy.
There are 3 types of decomposition reaction :
1. Thermal Decomposition - Decomposition by heat energy
E.g: CaCO₃ + Heat Energy ( Δ ) ==> CaO + CO₂
2. Electrolytic Decomposition: Decomposiition by electrical energy
E.g: 2H₂O + Electric Energy ==> H₂ + O₂
3. Photolytic Decomposition: Decomposition by Photon or Light energy.
E.g: 2AgCl + Light Energy ==> 2Ag + Cl₂
In this case: Light Energy is the Sunlight
Therefore while AgCl₂ ( White Powdery Substance ) is decomposed, it gives a greyish precipitate of Silver ( Impurities present ) along with the liberation of Chlorine gas ( Bleaching Powder smell ).
This type of chemical reaction can be called as Photolytic Decomposition Reaction.
Hope it helped :-)
