The given reaction [tex]BaCO_3 \rightarrow BaO + CO_2[/tex] is the thermal decomposition reaction.
Explanation:
- Barium carbonate [tex](BaCO_3)[/tex] is decomposed thermally to produce oxide barium [tex](BaO)[/tex] and carbon dioxide [tex](CO_2)[/tex]. This reaction generally takes place at a temperature of 1000-1450°C.
- Here, the reactant, Barium Carbonate appears like white crystals, Oxide barium is a white solid and carbon dioxide is a colorless gas.
- The reaction can as also be stated as a gas forming reaction since the by product is in gaseous state.
