✓ Answer: A Photolytic decomposition reaction
In this reaction, silver chloride (AgCl) breaks down into silver (Ag) and chlorine gas (Cl2) when exposed to ultraviolet light. This type of reaction, where a compound decomposes due to light, is known as photolytic decomposition. The chemical equation is: 2AgCl(s) → 2Ag(s) + Cl2(g).
