Question 1

In the industrial production of calcium oxide (quicklime), calcium carbonate is thermally decomposed according to the following equation:

CaCO3(s)→CaO(s)+CO2(g) \text{CaCO}_3(\text{s}) \rightarrow \text{CaO}(\text{s}) + \text{CO}_2(\text{g}) CaCO3​(s)→CaO(s)+CO2​(g)

Explain the effect on the atom economy of this process if the carbon dioxide byproduct is captured and sold to fire extinguisher manufacturers.
