The equation 2H2SO4 -> 2SO2 + 2H2O + O2

1. Detailed information about the chemical equation:

The complete equation of the reaction is 2H₂SO₄ -> 2SO₂ + 2H₂O + O₂ -> . This reaction involves the decomposition of sulfuric acid (H₂SO₄) into sulfur dioxide (SO₂), water (H₂O) and oxygen (O₂).

2. Reaction conditions:

This reaction requires high temperatures (from 400 to 800 degrees Celsius) to occur.

3. Reaction process:

When sulfuric acid is heated at temperatures from 400 to 800 degrees Celsius, it decomposes into sulfur dioxide, water, and oxygen. This decomposition is a simple process, in which the H₂SO₄ molecules become unstable and break down into other products.

4. Phenomena occurring:

The phenomena that occur in this reaction are the escape of sulfur dioxide gas, oxygen gas, and water vapor. This is a thermal decomposition reaction, thus it requires a high amount of heat to initiate. Also, there may be a color change when the reaction takes place due to the formation of sulfur dioxide.
