The equation for aerobic production of acetic acid from ethanol is:

CH2OH+O2→CH3CO2H+H2O.

(ethanol) (acetic acid)

Acetobacter aceti bacteria are added to vigorously-aerated medium containing 10 g.14 ethanol. After some time, the ethanol concentration is 2 g.-2 and 7.5 g.11 of acetic acid is produced. What is the observed yield (Yoing-) and theoretical yield (Yting-8") of acetic acid from ethanol?
