The formation of ethyl alcohol (C2H5OH MM
= 46.08 g/mol) by the fermentation of glucose
(C6H12O6 MM = 180.18 g/mol) may be
represented by:
C6H12O6 →
2C2H5OH + 2CO2
If a particular glucose fermentation process is 87.0% efficient,
how many grams of glucose would be required for the production of
56.0 g of ethyl alcohol (C2H5OH)?

Determine the ∆Sº and ∆Gº using Appendix G for the following
reaction.
C2H5OH(l) + 3 O2(g)
--> 2 CO2(g) + 2 H2O(l)
Report your answer to four sig figs. Omit unit labels. Only add
a - number is the sign is negative. Adding a + to a positive answer
messes up the grading.
