In decomposition reaction a compound splits up into two or more simpler substances. The reactions are carried out by applying heat, light or electricity.

Thermal decomposition:
When a decomposition reaction is carried out by heating it is called thermal decomposition reaction.

CaCO₃ (s) -----heat> CaO(s) + CO₂(g)

Electrolytic decomposition:

When a decomposition reaction is carried out with the help of electric current it is called electrolytic decomposition reaction. This process is also called electrolysis.

2H₂O(l) -----electric current> 2H₂(g) + O₂(g)
