उत्तर
Photolytic Decomposition is the process by which silver chloride breaks down into silver and chlorine when exposed to sunlight. Silver metal and yellowish chlorine gas are the byproducts of the breakdown of white silver chloride.
The chemical reaction is given as follows:
\[\ce{2AgCl(s) ->[Light][Decomposition]2AgCl(s) + Cl2(g)}\]
