P8-11 (a-j) ILLUDLU Complete parts a-h by hand For part i, a pressure drop term is given but the differential equation: dy a TFF dV 2y To Fro Is valid with the key difference being that the pressure drop term (a) is no longer the same as it is for the PBR. Though it is not necessary to solve the problem, the definition for the pressure drop term in a PFR is found on pg. 191 of your textbook. P8-11.

(Ang: 400 dm') h. What are the exit molar flow rates from the 400 dm'CSTR? Note: The following parts require an ODE solver and are of "Blevel" difficulty 1. PFR. Now assume the reactions take place in the gas phase. Use the preceding data to plot the molar flow rate's selectivity and p as a function of PFR volume up to 400 dm! The pressure-drop parameter is 0.001 dm-, the total concentration entering the reactor is 0.2 mol/dm', and v, - 100 dm /min. What are the values ore of and SCD? 1. Membrane Reactor.
