What are the advantages/disadvantages of using the fermentation of glucose to manufacture ethanol.Advantages: Uses continuous process which is efficient. Uses renewable resources, e.g sugar cane. Pure product. Disadvantages: Slow rate of reaction. High temperature and pressure require high energy input .Advantages: Uses continuous process which is efficient. Uses renewable resources, e.g sugar cane. Low temperature and pressure so low energy input. Disadvantages: Slow rate of reaction. Impure product.Advantages: Uses renewable resources, e.g sugar cane. Pure product. Disadvantages: Uses batch process which is inefficient. Slow rate of reaction. High temperature and pressure require high energy input .Advantages: Uses renewable resources, e.g sugar cane. Uses low temp and pressure therefore low energy input. Disadvantages: Uses batch process which is inefficient. Slow rate of reaction. Impure product.Question 4 of 14 Loading... 5.

What is the functional group of alcohols?-OH-COOH-C=C--C-C-Question 12 of 14 Loading... 13. In the production of ethanol by fermentation, why is the process done in the absence of air?If air were present the alcohol would oxidise to make an esterIf air were present the yeast would not be able to survive as they can only respire anaerobicallyIf air were present the yeast would respire aerobically, producing carbon dioxide and water, instead of ethanolIf air were present the ethanol produced would be impure because it would have gases from the air dissolved in itQuestion 13 of 14 Loading... 14.
