P6-21 B. The gas-phase reactions take place isothermally in a membrane reactor packed with catalyst. Pure A enters the reactor at 24.6 atm and 500K and a flow rate of A of 10mol/min AB+CAD2C+D2EriC=kIC[CAKICCBCC]r2D=k2DCAr3E=k3ECC2CD Only species B diffuses out of the reactor through the membrane. (a) Plot the concentrations down the length of the reactor. (b) Explain why your curves look the way they do. (c) Vary some of the parameters (e.g.,kB.k1,KIC) and write a paragraph describing what you find.
