Solution
The correct option is A Decomposition reaction
Silver chloride decomposes to two different products i.e. silver and chlorine.
The balanced chemical equation is:
2AgCl(s) → 2Ag(s) + Cl2(g)
Such chemical reaction in which two or more products are formed from a single reactant is called a decomposition reaction.
It is a decomposition reaction that occurs in the presence of sunlight and hence it is a photochemical decomposition reaction.
