Question

Give an example of decomposition reaction using elctric energy

Answer 1

Electrolytic decomposition may result when electric current is passed through an aqueous solution of a compound. A good example is the electrolysis of water. Electrolysis of water: Electrolysis of water is thedecomposition of water into hydrogen and oxygen due to the passage ofelectric current through it.

Answer 2

$2H2O\frac{electric}{current} > 2H2 + O2$
Hope it's clear.
