Catalytic oxidation of \(\mathrm{CO}\) is an important reaction in pollution prevention. The reaction scheme is

\[\mathrm{O}_{2}(\mathrm{~A})+2 \mathrm{CO}(\mathrm{B}) \rightarrow 2 \mathrm{CO}_{2}(\mathrm{C})\]

Set up the Stefan-Maxwell model for this problem. State the determinacy condition and simplify the equations into two differential equations for the mole-fractions of any two of these species. Calculate the solution for the mole-fraction profiles and find the values of the fluxes using the matrix method and the BVP method. Assume fast reaction at the catalyst surface.
