2. For non-catalytic reach A(g) + bB(s) Products which slep will control in the following cause Concentration of gas-phase reactant CAS As = CAC 1 R Gas film 7 R Te O Radial position Surface of shrinking unreacted core Surface of particle Concentration in main body of gas For irreversible reaction CAc=0 Correlate the time required for full conversion of B with R and re for the above case. 2.b) 5 Zymomonas mobilis cells are used in a CSTBR of 60 m capacity. Feed contains 12g/L glucose. If Ks = 18, Yc/s = 69, Hmax = 0.3h-, m = 2.2h- a) What flow rate is required for a steady state substrate concentration of 1.5g/L? b) At this flow rate what is the cell concentration? S
