Photochemical decomposition reaction is a type of chemical reaction that occurs when a substance is exposed to light, resulting in its decomposition into simpler compounds. This process is commonly used in the production of various chemical compounds and materials.

Process of Photochemical decomposition reaction

The process of photochemical decomposition reaction involves the following steps:

1. Absorption of light: The substance to be decomposed absorbs light energy from a light source.

2. Excitation: The absorbed light energy causes the electrons in the substance to become excited and move to higher energy levels.

3. Decomposition: The excited electrons react with other molecules in the substance, causing it to decompose into simpler compounds.

Applications of Photochemical decomposition reaction

Photochemical decomposition reactions have a wide range of applications in various fields such as:

1. Photolithography: This process is used in the semiconductor industry to create microchips and other electronic components.

2. Photography: Photochemical reactions are used in photography to develop film and create prints.

3. Polymerization: Photochemical reactions are used in the production of polymers, such as plastic, by causing the monomer molecules to react and form long chains.

4. Water treatment: Photochemical reactions are used to purify water by breaking down organic compounds and killing bacteria and other microorganisms.

Conclusion

In conclusion, photochemical decomposition reaction is a process that occurs when a substance is exposed to light, resulting in its decomposition into simpler compounds. This process has a wide range of applications in various fields, including the production of electronic components, photography, polymerization, and water treatment.
