Aerobic degradation of benzoic acid by a mixed culture of microorganisms can be represented by the following reaction: C6H5COOH+aO2+bNH3cC5H7NO2+dH2O+eCO2 where C6H5COOH is the substrate, and C5H7NO2 is the bacteria. Determine a,b,c,d and e, knowing that 0.9 moles of CO2 are produced per mole of O2 consumed. a=5b=0.5c=0.5d=2e=4.5 a=4.5b=2.4c=2.4d=1.8e=5 a=4.5b=2.4c=2.4d=1.8e=5 a=2.73b=0.91c=0.91d=0.73e=2.45 a=3b=0.48c=0.48d=4.32e=3.12 none of the above
