Question:

3. To reduce the amount of nitric oxide emitted from cars, we use catalytic converters, where NO + CO react on the catalyst surface to form CO, and N, via a first order reaction with a rate constant of 0.005 m/s (more information is given in the diagram below). The NO diffuses to the catalyst surface (Doco 10* m/s) Determine: a. The molar concentration of CO at the catalyst surface. b. The rate of removal of CO at the surface. c. The rate of removal if the process is diffusion limited. SCHEMATIC: Exhaust gases .kbar XAL 015 Mixture, DAB:104m2/s As.MA,s NO Catalytic surfaceX
