The lactic acid fermentation of glucose produces lactic acid.
C6H12O6 (s) ⇌ 2 C3H6O3 (l)
While the anaerobic fermentation of glucose produces ethanol and carbon dioxide.
C6H12O6 (s) ⇌ 2 C2H5OH (l) + 2 CO2(g)
Make a comparison between the equilibrium constants for the reactions.
(ΔG°f C6H12O6 (s) = -910.4 kJ/mol, ΔG°f C3H6O3 (l) = -711.62 kJ/mol, ΔG°f C2H5OH (l) = -174.8 kJ/mol, ΔG°f CO2(g) = -394.4 kJ/mol)
