The industrial production of bioethanol by the anaerobic fermentation of glucose also produces carbon dioxide as a by-product:
C6H12O6(aq)→2C2H5OH(aq)+2CO2(g) \text{C}_6\text{H}_{12}\text{O}_6\text{(aq)} \rightarrow 2\text{C}_2\text{H}_5\text{OH(aq)} + 2\text{CO}_2\text{(g)} C6H12O6(aq)→2C2H5OH(aq)+2CO2(g)Explain how the overall atom economy of this manufacturing process can be improved.
