The rate constant is k=0.1 L.mol'.min. The initial charge to the reactor contains 9 moles of A and 1 mol of inert. i- ii- Calculate the moles of B after 10 minutes of operation. Calculate the time required to achieve 90% conversion Question #2 (6 points) Consider the elementary gas phase reaction A+ 2B3C that takes place in a plug flow reactor operated isothermally and isobarically. The feed to the reactor contains A-25%; B=64% and the balance is inert. The feed molar flow rate is 10 mol/s and the feed enters at 5 atm and 400 K. The rate constant, k, is 0.5x10' L.mols All % are molar percentage. Write a PolyMath computer program that determines the conversion of component "A" if the reactor volume is 1.3 L. Question #3 (7 points) 0.5 The following nonelementary, liquid phase reaction A+ 2BC takes place in two isothermal CSTRS connected in series. The rate of the reaction is -r=0.307 CA5 C2-5 mol/L/min. The feed to the first reactor contains A-30%mol; B-60% mol: Inert(1) -10%mol and its total feed volumetric flow rate is 5 L/min and the feed concentration of "B" is 6.0 mol/L.
