Question
Differentiate between the following:
Electrolytic decomposition and photochemical decomposition.
Solution
Electrolytic decomposition and photochemical decomposition:
- Electrolytic decomposition : “A chemical reaction which takes place with absorption of electrical energy”
\[\ce{\underset{\text{collected at}}{2H2O}->[electric][current]\underset{\text{cathode}}{2H2} + \underset{\text{anode}}{O2}}\] - Photochemical decomposition: “A chemical reaction which takes place with the absorption of light energy”
\[\ce{H2 + Cl2->[sunlight]2HCl}\]
