Question

Differentiate between electrolysis and photolysis with suitable example

Answer 1

Refer to the attachment...

Answer 2

Answer:

●Electrolysis -: When decomposition reaction is done by electricity is termed electrolysis decomposition reaction.

=)Example - 2H2 + O2 = 2H2O ( by electricity )

●Photolysis -:When decomposition reaction is done by sunlight is termed photolysis decomposition reaction.

=) Example - 2AgBr = 2Ag + Br2 ( by sunlight )

Explanation:

★ Photolysis:- When decomposition reaction is occurred by sunlight. This reaction is known as Photolysis.

For Example:

2AgCl(s) → 2Ag(s) + Cl2(g)

Due to sunlight or photons

★ Electrolysis:- When decomposition reaction is occurred by electricity. This reaction is known as Electrolysis.

For Example:

2H2O(l) → 2H2(g) + O2 (g)

Due to electricity.
