In which type of decomposition reaction does light energy help break down a compound?
Answer and explanation
Correct answer: Photolytic decomposition
In photolytic decomposition, light energy helps break chemical bonds in a compound. For example, silver chloride decomposes in sunlight: \(2\mathrm{AgCl}\xrightarrow{\text{sunlight}}2\mathrm{Ag}+\mathrm{Cl}_2\). In contrast, electrolytic decomposition uses electrical energy, whereas thermal decomposition uses heat energy.
