what is thermal decomposition ,electrolytic decomposition and photolytic decomposition. explain with diagram and examples. it's urgent plz solve carefully.
Answers
Hey Khulana, here's your answer -
Decomposition refers to the breakdown of any substance. Therefore,
- Thermal Decomposition - breakdown by action of heat, example breaking of chemical bonds by action of heat.
- Electrolytic Decomposition - breakdown by action of electricity.
- Photolytic Decomposition - breakdown by action of photon (sunlight).

⭐Answer⭐
Types of decomposition reaction :-
Thermal decomposition reaction:-
A thermal decomposition reaction can be defined as a decomposition reaction which is activated by thermal energy. The reaction is generally endothermic as energy is required to break chemical bond in order to separate the constituent elements.
example of thermal decomposition reaction
CaCO3 → CaO + CO2 When heated Calcium Carbonate,decomposes into Calcium Oxide and Carbon Dioxide. This process is employed in the manufacturing of quick lime which is an important component in industries.
Electrolytic decomposition reaction:-
An electrolytic decomposition reaction is a type of decomposition reaction in which the activation energy for decomposition.
example of electrolytic decomposition reaction
Dissociation of water:2H2O→ 2H2 + O2
Photo decomposition/ photolytic decomposition/ photochemical decomposition:-
A photo decomposition is the type of decomposition reaction in which the reactant is broken down to its constituents by photons.
example of photo decomposition reaction
O3 + hν → O2 + O(1D)Photolysis occurs in the atmosphere wherein ozone molecules is broken down into oxygen molecule and atomic oxygen.
