Practice question
Question
Acetobacter aceti converts alcohol to acetic acid according to the stoichiometric relation C2H5OH + O2 → CH3COOH + H2O In a vigorously agitated and aerated reactor containing 20 g/l ethanol, the organism produces 16 g/l acetic acid and 2 g/l was the residual ethanol concentration. What are the theoretical and observed yields of acetic acid expressed in g/g ethanol?
Explanation
quantitative reasoning analysis shows ratio, percentage and series logic determine correct calculation. Consequently 60/46 and 16/18 emerges as the valid choice since it meets mathematical and logical criteria, aligning with established principles in aptitude and reasoning literature.
