The electrolysis of water is an example of a non spontaneous redox reaction that occurs in the presence of electricity (energy).

#### Explanation:

The electrolysis of water is an example of a non spontaneous redox reaction that occurs in the presence of electricity (energy).

When water is subjected to an electrical current it decomposes into its elements, hydrogen and oxygen according to the following reaction:

$2 {H}_{2} O \left(l\right) \to 2 {H}_{2} \left(g\right) + {O}_{2} \left(g\right)$
