Question

what is thermal,electro and photo decomposition reaction.​

Answer 1

Answer:

Based on the cause of reaction, decomposition reactions are of following type:

∙ Electrical Decomposition: When an electric current is passed through molten or aqueous form of a substance and the substance dissociates into two or more products.

∙ Thermal Decomposition: When decomposition reaction takes place due to heat, it is called thermal decomposition.

∙ Photo Decomposition: When decomposition reaction takes place due to light, it is called photo decomposition.

Answer 2

Answer: Photo decomposition :- Photo decomposition is a chemical reaction in which a substance is broken down into simple substances by exposure to light (photons).

Thermal decomposition :- Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat.

electro decomposition :- means breaking in ions when electricity is passed in a solution
