Need step by step written solution for a,b,c,d,e

Dilute aqueous solution of acetic anhydride is to be hydrolyzed continuously at 25C. at this temperature, the equation is rA=0.175C gm mole /cm3min.C= concentration af acetic anhydride, gmmole/cc. The feed rate is 500cm3/min of solution and initial concentration of acetic anhydride is 1.4104gmmole/cc. Calculate the final corversion for the following: a) single CSTR (Volume 4 lt) b) Two single CSTR in parallel (each 2 It). c) Two CSTR (each 2 lt volume) in series. d) CSTR followed by plug flow (each 2 It). e) Tubular followed by CSTR (each 2 It). 15[CO1 and CO2]
