Question
What is ∆Hºrxn for the fermentation of glucose as shown below?
C6H12O6(s) → 2 C2H5OH(l) + 2 CO2(g) ∆Hºrxn = ???
C2H5OH(l) + O2(g) → CH3COOH(l) + H2O(l) ∆Hºrxn = –492.6 kJ mol–1
CH3COOH(l) + 2 O2(g) → 2 CO2(g) + 2 H2O(l) ∆Hºrxn = –874.2 kJ mol–1
C6H12O6(s) + 6 O2(g) → 6 CO2(g) + 6 H2O(l) ∆Hºrxn = –2805.0 kJ mol–1
A.✓ Correct
–71.4 kJ mol–1
B.
–945.6 kJ mol–1
C.
–1438.2 kJ mol–1
D.
–5528.7 kJ mol–1
