bulk gas stream containing 0.10 mole % of carbon monoxide (CO) gas, 2.0 mole %O2 gas, and 97.9mole% of CO2 gas flows over a flat catalytic surface of length 0.50m at a bulk velocity of 40m/s at 1.0 atm and 600K. Heat-transfer processes maintain the gas stream and catalytic surface at 600K. At this temperature, the catalytic surface promotes the oxidation reaction CO(g)+1/2O2(g) CO2 (g). Let A=CO,B=O2,C=CO2. The gas-phase diffusion coefficients at 1.0 atm and 300K are DAB=0.213cm2/s,DAC= 0.155cm2/s,DBC=0.166cm2/s. a. What are the Schmidt numbers for CO and O2 mass transfer? What species (CO,O2,CO2) is considered the carrier gas? b. For CO mass transfer, what is the average convective masstransfer coefficient (kc) over the 0.50m length of the catalytic surface, and the local mass-transfer coefficient (kc,x) at the far edge of the catalytic surface (x=L=0.50m) ? c. Using boundary-layer theory, scale kc for CO mass transfer to kc for O2 transfer. d. At 600K, the surface reaction constant for the first-order oxidation reaction with respect to CO concentration is ks=1.5cm/s. What is the average molar flux of CO to the catalytic surface, assuming that the composition of CO in the bulk gas is maintained at 0.10 mole\%
