Solution
- Electrolytic decomposition: “A decomposition reaction which is brought about by the passage of electric current.”
\[\ce{2H2O->[Electricity][Current]2H2 + O2}\] - Photochemical decomposition: “A decomposition reaction which takes place in presence of light.”
e.g. decomposition of silver salts in the presence of sunlight.
