a) is answered already.

please answer b) c) d) and e)

did you see the answered part a)

still can't do it?

4. A researcher proposes a process that produces 1% ethanol by volume. a. Using the graph presented in the notes, how much steam (kg steam/gal anhydrous ethanol) is required to distill the ethanol to purity? (Note: Use the practical" curve not the "theoretical" curve.) - 26.5 b. Based on the density of anhydrous ethanol, express the distillation energy requirement as kg steam/kg anhydrous ethanol. c. Assuming the steam has a latent heat of 2000 kJ/kg, how much energy (kJ/kg anhydrous ethanol) is required? d. Express the distillation energy requirement as a fraction of the lower beat of combustion for anhydrous ethanol, i.e., kJ distillation energy combustion energy e. If this process is used to make biofuels, briefly describe your perspective on the practicality of this approach
