Answer:
Since decomposition of silver chloride takes place in the presence of sunlight, so it is a photolytic decomposition reaction.
Photolytic decomposition reaction
A photodecomposition reaction is a type of decomposition reaction in which the reactant absorbs energy from photons and breaks down into its constituents. The decomposition into dioxygen and an oxygen radical, as illustrated by the chemical equation given below, is an example of a photo decomposition reaction.
O3 + hν → O2 + O.
Application of photolytic decomposition reaction
- Decomposition reactions are used in the manufacture of cement and calcium oxide.
- Thermite welding.
- Separation of metals from oxides, chlorides, and other metallurgical processes.
