The above equation describes the decomposition process of calcium carbonate (CaCO3) through high temperature to form calcium oxide (CaO), carbon dioxide (CO2) and oxygen (O2).
- Conditions for the Reaction
The reaction requires high temperature (around 825-900 degrees C) to occur.
- Reaction Process
When the temperature is raised high enough, the molecules of calcium carbonate start to decompose into calcium oxide, carbon dioxide and oxygen molecules.
- Phenomena Occurring
During the reaction process, if performed in a sealed container, you will see CO2 and O2 gases being released. Additionally, calcium oxide will be formed as a solid substance. In industrial processes, this reaction is usually performed in a furnace at very high temperatures.
