Question 1: (10 Marks) Anaerobic digestion of volatile acids by methane bacteria is represented by the equation: CH3COOH + NH3 → biomass + CO2 + H2O+ CH4 (acetic acid) (methane) The composition of methane bacteria is approximated by the empirical formula CH1.400.40N0.20. For each kg of acetic acid consumed, 0.67 kg of CO₂ is evolved. How does the yield of methane under these conditions compare with the maximum possible yield? Useful Formula: f max wxYs јхүр Data: Yps=0.67 kg/kg=0.67 g/g ; Ys=4.00; Yp=8.00 ; MM C = 12g/mol; MM O = 16g/mol; MM H = 1g/mol; MM N = 14g/mol; Ammonia is the reference.
