Unformatted text preview: as a uniform mass with a specific heat capacity of 0.86 cal/g/C. Bioreactor Problem Consider a thermophilic bacterium that converts glucose into acetic acid by the overall reaction: C 6 H 12 O 6 (s) + 2 O 2 (g) 2 CH 3 COOH (l) + 2 CO 2 (g) + 2 H2O (l) a) Calculate H for this reaction at 80C and 1 atm. b) Estimate G for this reaction at 80C and 1 atm. Is it spontaneous? c) If 80 g/L glucose is completely converted by this bacterium at 80C and 1 atm in a fermentation bioreactor, what will be the rise in temperature of the fermentation broth (you can assume that physical properties of the broth are identical to those of water). Use data from tables A.5-7 in Tinoco. Other physical properties that may be useful: Cp (J/mol/C) Mol Weight (g/mol) Acetic acid (l) 123.5 60 Glucose (s) 225 180 H 2 O (l) 75 18 O 2 (g) 29 32 CO 2 (g) 37 44...
