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.
