Question Question 4.2
Differentiate between the following :
Electrolytic decomposition & photochemical decomposition
| Electrolytic decomposition | Photochemical decomposition |
|---|---|
| A decomposition reaction which is brought about by passage of electric current is known as Electrolytic decomposition. | A decomposition reaction which occurs in the presence of light is known as Photochemical decomposition. |
| For example: 2H2O ⟶ 2H2 + O2 (On Passage of Electric Current) | For example: 2AgCl ⟶ 2Ag + Cl |
