A decomposition reaction is a type of reaction in which one compound breaks down into two or more elements. This can be represented by the general equation: AB → A + B. The examples of decomposition reactions is the breakdown of hydrogen peroxide into water and oxygen atoms and the breakdown of water into hydrogen and oxygen atoms. There are three types of decomposition reaction i.e. Thermal Decomposition Reaction, Electrolytic Decomposition Reaction and Photo Decomposition Reaction.
So we can conclude that In a decomposition reaction the one compound is broken down into more atoms.
