Bioethanol (C2H5OH) can be produced from starch in corn, sugar in sugar cane, or cellulose from the cellulosic biomass. The simplied chemical reactions for hydrolysis and fermentation are: C12H22O11 +H2O ===> 2C6H12O6 2C6H12O6===> 2C2H5OH + 2CO2 Hence, the overall reaction can be described as C12H22O11 +H2O 4C2H5OH + 4CO2 a) What is theoretical maximum emission rate of CO2 when a biofuel company plan to produce 10 kg Bioethanol every day? Note: The molar weights of C12H22O11, C2H5OH and CO2 are 342, 46, and 44 g/mol,respectively. b) Plug in 75 kg (average weight of an adult), we have 19 mL of CO2/breathe with about 70 breath/minute. And the typical adult diet in wealthy countries like Canada is about 600 g/day of food (dry basis). Calculate the emission factor for CO2 by human (g CO2/g food).

Note: Assume the pressure to be 1 atm and the temp is 25 C.
