Question

mention and explain with an example for each The Three Types of decomposition reaction ?​

Answer 1

Answer:

decomposition reaction-

A decomposition reaction can be defined as a type of chemical reaction in which under suitable conditions, one single compound splits into multiple simpler substances.

Explanation:

Types of decomposition reaction

Let us look at the three main types of decomposition reactions which we see around us.

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.

Answer 2

Explanation:

Decomposition reactions can be classified into three types: ☆Thermal decomposition reaction.

☆Electrolytic decomposition reaction.

☆Photo decomposition reaction....
