Question 3. ( 6 points) The following first-order reaction is taking place in a PBR. AB The reaction rate and the rate constant are given by: rA=kpAmol(kggcat.h)k=0.75mol(atmkg cat.h) A is fed to the reactor with 50% inerts at 327C and 1 atmosphere. Feed rate of A is 37.5 moles h. The pressure drop parameter a=0.0045kg1. Obtain an expression that relates the conversion in the reactor to the weight of the catalyst used. State your assumptions. What conversion can you obtain with 100kg of the catalyst? ax+b1dx=a1ln(ax+b)(ax+b)ndx=a(n+1)(ax+b)n+1 PA=yAP PV=nRTP0V0=n0RT0PV=nRT
