The chemical equation shows that when potassium oxide (K2O) reacts with carbon dioxide (CO2), it forms the compound potassium carbonate (K2CO3). This reaction has a mole ratio of 1:1:2, that is, one mole of K2O and one mole of CO2 will form two moles of K2CO3.
- Reaction conditions
This reaction requires the presence of high temperature or suitable catalyst to occur.
- Reaction process
During the reaction process, molecules of K2O will combine with molecules of CO2 to form molecules of K2CO3. This combination occurs at the atomic level, when potassium atoms in K2O combine with carbon and oxygen atoms in CO2 to create a new compound.
- Phenomena occurrence
The phenomena occurring in this reaction are quite difficult to observe with the naked eye because both the products and reactants are either solid or colorless, odorless gases. However, if the reaction is conducted under laboratory conditions, one can observe the release of heat – a sign that a chemical reaction is taking place.
