Write one equation each for decomposition reactions in which energy is supplied in the form of heat, light or electricity.

(a) Thermal decomposition reaction (Thermolysis )

Potassium chlorate decomposition: Potassium chlorate breaks down into potassium chloride and oxygen when heated strongly. The production of oxygen is produced through this reaction.

2KClO₃ + Heat → 2KCl + 3O₂

(b) Electrolytic decomposition reaction (Electrolysis)

Sodium chloride decomposes into sodium and chlorine when electricity is applied to molten sodium chloride.

(c) Photodecomposition reaction (Photolysis)

Hydrogen peroxide decomposes in the presence of light, producing water and oxygen.
