Question

difference between electrolytic decomposition and photochemical decomposition.

Answer 1

Hey dear
Here is ur answer
Photochemical decomposition :-
These reactions involve absorption of light.The presence of light is the primary requisite for the reaction to take place Temperature has very little effect on the rate of a photochemical reaction. Instead, the intensity of light has a marked effect on the rate of a photochemical reaction.

Electrolytic decomposition :-
Is breaking of compounds in ions when electricity is passed in a solution.
Ex:
When we pass electricity in a solution of Na-Cl and water NaCl is broken in ions. Or electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to an electric current being passed through the water.
Hope it helps u dear
Have a great day

Answer 2

Electrolytic =it is ➗ by two product
Photochemical =it is ➗ into more products
