The concentration of oxygen at z=δ is 21 mole percent. The reaction at the surface may be assumed to occur instantaneously. No reaction occurs in the gas film. What would be the form of the equation providing the flux of oxygen if (a) only carbon monoxide is produced on the carbon surface; (b) only carbon dioxide is produced on the carbon surface; (c) the following instantaneous reaction occurs on the surface, 4C+3O2→2CO+2CO2.
In a hot combustion chamber, oxygen diffuses through air to a flat carbon surface
where it reacts to produce CO and/or CO2.
Reduce the general differential equation for mass transfer to write a specific
differential equation for oxygen that will describe the steady-state mass transfer process.
