A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

What are the 3 decomposition reaction?

Decomposition reactions can be classified into three types: Thermal decomposition reaction. Electrolytic decomposition reaction. Photo decomposition reaction.
