Explanation of the Reaction:

The given reaction is a decomposition reaction in which ferrous sulfate (FeSo4) decomposes to form ferric oxide (Fe2O3), sulfur dioxide (SO2), and sulfur trioxide (SO3). This reaction is also known as the thermal decomposition of ferrous sulfate.

Thermal Decomposition:

Thermal decomposition is a process in which a compound breaks down into simpler substances when heated. In this reaction, ferrous sulfate breaks down into ferric oxide, sulfur dioxide, and sulfur trioxide when heated to a high temperature.

Reaction Mechanism:

The thermal decomposition of ferrous sulfate can be represented by the following equation:
2FeSO4 → Fe2O3 + SO2 + SO3

When ferrous sulfate is heated, it loses its water of crystallization and forms anhydrous ferrous sulfate. This anhydrous ferrous sulfate further decomposes into ferric oxide, sulfur dioxide, and sulfur trioxide.

FeSO4 → FeO + SO2 + 1/2O2
2FeO → Fe2O3 + 1/2O2
2SO3 → 2SO2 + O2

Applications of the Reaction:

The thermal decomposition of ferrous sulfate has various applications in industries. Some of them are:

1. As a source of iron oxide for pigments and paints
2. As a reducing agent in the production of iron and steel
3. As a catalyst in the manufacture of sulfuric acid

Conclusion:

The given reaction is a thermal decomposition reaction in which ferrous sulfate decomposes to form ferric oxide, sulfur dioxide, and sulfur trioxide. This reaction has various applications in industries, and it is important to understand its mechanism to utilize it effectively.

This reaction is called decomposition reaction because one substance split up into two or more simpler substances .
