The liquid phase hydrolysis of acetic anhydride to form acetic acid is

to be carried out in a I liter CSTR and in a 0.311 liter PFR. The volumetric flow rate to in each case is 3.5 x 10^{- 3}
dm³/s. The reaction follows an elementary rate law with a specific reaction rate of 2 x 10⁴
dm³/mol · s. The concentrations of acetic anhydride and water in the feed to the reactors are lM and 5l.2M respectively. Find the conversion in (a) the CSTR and (b), the PFR.
