The reaction A - B is to be carried out isothermally in a continuous-flow reactor. The entering volumet- ric flow rate v, is 10 dm/h. (Note: FA = CAU. For a constant volumetric flow rate v = Vo, then FA = C Vo. Also, CA = FA/V, = ([5 mol/h][10 dm3/h]) 0.5 mol/dm3.) Calculate both the CSTR and PFR reactor volumes necessary to consume 99% of A (i.e., CA = 0.01CA0) when the entering molar flow rate is 5 mol/h, assuming the reaction rate -ra is: (a) -ra = k with k = 0.005 [Ans.: VPFR = 921 dm3] hdm3 (b) -ra = kCA with k = 0.0001 - (C) -ra = kC with k = 0.3 [Ans.: VCSTR = 660,000 dm?] mol.h (d) Repeat (a), (b), and/or (e) to calculate the time necessary to consume 99.9% of species A in a 1000 dm constant volume batch reactor with CAO = 0.5 mol/dm3. mol dm3 a
