The chemical equation is Li2O + 2SO2 -> 2Li2SO3

Detailed information about the Li₂O + 2SO₂ -> 2Li₂SO₃equation
This chemical equation describes the reaction process between lithium oxide (Li₂O) and sulfur dioxide (SO₂) to form lithium sulfite (Li₂SO₃). From the equation, it can be seen that each Li₂O molecule reacts with 2 SO₂ molecules to produce 2 Li₂SO₃ molecules.

Reaction conditions
This reaction usually occurs at high temperatures.

Reaction process
The reaction process takes place when Li₂O molecules come into contact with SO₂ molecules. Oxygen from Li₂O combines with sulfur from SO₂ to form sulfite, while lithium from Li₂O combines with oxygen from sulfite to form Li₂SO₃. This process continues until one of the two reactants is exhausted.

Phenomena occurring
During the reaction process, there may be changes in color, temperature, and/or pressure. However, specific information about these phenomena in this reaction is not clearly recorded in the available information source.
