The hydrolysis of acetic anhydride to form acetic acid is carried out in a 1250 litre CSTR. The feed is 2.5 mol/L acetic anhydride and 50 mol/L of water. The reaction (CH3CO)2O + H2O <---> 2CH3COOH is first order in (CH3CO)2O and first-order in H2O at the reactor temperature. The rate constant is 0.075 L/(mol-s). The feed flow rate is 15 L/s. What is the conversion of acetic anhydride?
