Ethanol (ch 3 ch 2 oh) is dehydrogenated in the presence of air over a catalyst, and the following reactions take place: ch3 ch2 oh → ch3 cho + h2 2ch3 ch2 oh + 3o2 → 4co2 + 6h2 2ch3 ch2 oh + 2h2 → 4ch4 + o2 separation of the product, ch3 cho (acetaldehyde), as a liquid leaves an output gas with the following orsat analysis: co2 0.7%, o2 2.1%, co2.3%, h2 7.1%, ch4 2.6%, and n2 85.2%. how many kilograms of acetaldehyde are produced per kilogram of ethanol fedinto the process?
