is this find in table? if yes which one \mu_CO = 0.01 g/(cm.s) \mu_02 0.02 g/(cm. s) 28.14 Consider the process shown in the figure (next page). A bulk gas stream containing 0.10 mole% of carbon monoxide (CO) gas, 2.0 mole% O2 gas, and 97.9 mole% of CO2 gas flows over a flat catalytic surface of length 0.50 m at a bulk velocity of 40 m/s at 1.0 atm and 600 K. Heat-transfer processes maintain the gas stream and catalytic surface at 600 K. At this temperature, the catalytic surface promotes the oxidation reaction CO(g) +1/202(g) → CO2(g). Let A=CO, B=O₂, C=CO2. The gas-phase diffusion coefficients at 1.0 atm and 300 K are DAB = 0.213 cm²/s, DAC= 0.155 cm²/s, DBC=0.166 cm²/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 mass- transfer coefficient (ke) over the 0.50 m length of the catalytic surface, and the local mass-transfer coefficient (kex) at the far edge of the catalytic surface (x=L=0.50 m)? c. Using boundary-layer theory, scale ke for CO mass transfer to ke for O₂ transfer. d. At 600 K, the surface reaction constant for the first-order oxidation reaction with respect to CO concentration is k, 1.5 cm/s.
