In a combustion chamber, oxygen diffuses through air to the carbon surface where it reacts to make CO and/or CO₂. The mole fraction of oxygen at x=0 is 0.21. The reaction at the surface may be assumed to be instantaneous. No reaction occurs in the gas film. Determine the rate of oxygen diffusion per hour through 1 m² of area if: 

a. Only carbon monoxide is produced at the surface 

b. Only carbon dioxide is produced at the surface 

c. Both CO and CO₂ are produced at the surface. Охуgen CO and/or CO2 Carbon
