Across a gas film of thickness of 0.2 mm, components A and B are diffusing in opposite directions at 2 bars and 25 degrees. Under steady-state conditions, total molar flux of A is twice that of B. Partial pressures of A at each side of the film are 0.40 bar and 0.10 bar. Calculate the total molar fluxes of A and B. Molecular diffusivity of A in B at 0 degrees and 1 bar is 2*10-5 m2 /s.
