A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds.
AB ----> A + B
Example
By heat-:
1) CaCO3 --> CaO + CO2
2) 2KClO3 --> 2KCl + 3O2
By light-:
1) 2AgCl --> 2Ag + Cl2
2) 2AgBr --> 2Ag + Br2
By electricity
1) 2H2O -->2H2 + O2
2) 2NaCl --> 2Na + Cl2

The reaction in which a single compound breaks into two or more products under specific conditions like heat, light and electricity is known as decomposition reaction.
For example:-
There are three types of decomposition reaction:-
1) Thermal decomposition reaction :- In this reaction, decomposition is carried out by heating the substance.
2) Photo Decomposition reaction:- In this reaction, decomposition is carried out by keeping reactant in sunlight.
3) Electrical Decomposition reaction:- In this reaction, decomposition is carried out by the passing electricity through reactant.
