The reaction rate and extent of reaction (rate constant and rate order) of acetic anhydride hydrolysis can be determined using different types of techniques. This reaction is fast and exothermic which can be regarded as irreversible as represented in Eq. 1. (CH3CO)2O + H₂O → 2CH3COOH (Eq. 1) The hydrolysis reaction takes place in a batch system at isobaric condition and perfectly mixed. Acetic anhydride is the limiting reactant with water in excess 10 times higher than acetic anhydride and first order with respect to water. The recorded data for several experiments are presented in Table 1 and Table 2. Table 1.

Q4 (CO2, PO2, C4) If acetic anhydride and water are introduced separately and these components are mixed before going into a reactor at 8 mol/L and 20 L/min. There are two types of reactors to choose from, either a 800-L PFR operates at 25 °C or a 200-L CSTR that operates at 77 °C. Given the rate constant, k is 0.07 L/mol•min with activation energy of 83.7 kJ/mol. Determine the
best reactor to run this hydrolysis reaction and specify the reactor conditions. Justify your answer. (20 marks)
