Question

write the type of decomposition reaction. with suitable example

Answer 1

A decomposition reaction occurs when one reactant breaks down into two or more products. ... Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

Answer 2

Answer: Decomposition is a type of chemical reaction in which one reactant forms two or more than two products.

Decomposition reactions require breaking of bonds which require energy and thus all of the decomposition reactions are endothermic reactions. They require energy in the form of heat, electricity or sunlight and thus called as thermal, electrolytic and photolytic decomposition respectively.

Example: $CaCO_3\rightarrow CaO+CO_2$   (thermal decomposition)

$2H_2O\rightarrow 2H_2+O_2$   (Electrolytic decomposition)

$2AgCl\rightarrow 2Ag+Cl_2$   (Photolytic decomposition)
