The decomposition of silver chloride into silver and chlorine in sunlight is a
Athermal decomposition
Bphotolytic decomposition
Celectrolytic decomposition
Dcombination reaction
Answer & Solution
Correct answer: B. photolytic decomposition
1. Decomposition can be driven by heat, light or electricity.
2. Light-driven decomposition is **photolytic**: 2AgCl → 2Ag + Cl₂ in sunlight.
3. This reaction is used in black-and-white photography.
