(a) These investigators reported that reaction is an elementary and the second-order rate constant for the reaction is equal to 1.15 x 10° m/(mol-s) at 20 °C. Determine the volume of Plug Flow Reactor (PFR) that would be necessary to achieve 40% conversion of the feed butadiene assuming isothermal operating conditions and a liquid feed rate of 0.500 x 10 m/s. The feed concentrations (in mol/m°) are as follows: Butadiene (B): 96.5 mol/m3 Methyl acrylate (M): 193 mol/m3 AICI3 (A): 6.63 mol/m 3.

(a) These investigators reported that reaction is an elementary and the second-order rate constant for the reaction is equal to 1.15 x 10° m°/(mol-s) at 20 °C. Determine the volume of Plug Flow Reactor (PFR) that would be necessary to achieve 40% conversion of the feed butadiene assuming isothermal operating conditions and a liquid feed rate of 0.500 x 10° m/s. The feed concentrations (in mol/m) are as follows: Butadiene (B): 96.5 mol/m Methyl acrylate (M): 193 mol/m³ AICI3 (A): 6.63 mol/m3 Plot the concentration profile (concentration versus the length of the reactor) of the reactants and products as the reaction taking place in the reactor. Discuss your predicted findings from your assumed range of tested data. Hint: Use Microsoft Excel for instance to test your concentration profile. (b) If the operating conditions used in question (a) are employed, determine the volume of a single Continuous Stirred-Tank Reactor (CSTR) which will give 40% conversion of butadiene when the liquid flow rate is 0.500 x 10 m/s.

Now consider, if the operating conditions are still used as in question (a) and (b) but the conversion of butadiene was found to be not achieving 40% for both PFR and CSTR. From your engineering assumptions, determine the factors that might cause the deficiency in the conversion.
