Unformatted text preview: H° for this reaction at 80°C and 1 atm. b) Estimate ∆G° for this reaction at 80°C and 1 atm. Is it spontaneous? c) If 80 g/L glucose is completely converted by this bacterium at 80°C and 1 atm in a fermentation bioreactor, how much heat is dissipated into the surroundings if the temperature is constant? d) If the bioreactor is insulated and no heat is allowed to escape, what would be the rise in temperature of the fermentation broth (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 H2O (l) 75 18 O2 (g) 29 32 37 44 CO2 (g) Sample Problem 3: Fever The basal rate of a “standard man” (150 lbs = 68 kg) is equal to 72 kcal/h. Heat losses occur due to radiation, evaporation, convection, and conduction. If you bundle up and your body compensates when you’re sick, you can shut down many of these (except radiation). Let’s suppose that you can shut down all of the body’s mecha...
