H2+O2H2O2 H2 and O2 diffuse through a gas film of 80m thickness to the palladium surface and a reaction occurred with the complete conversion of H2 and O2 to the H2O2 at 1 atm and 15C After the reaction, the H2O2 diffuses back through the same film into the bulk gas. At the bulk gas, the mole percents of the H2(A),O2(B) and H2O2(C) are 45,35 , and 20 respectively. The binary diffusivities at 1atm and 25C are given as DAC(H2H2O2)=1.7104m2/s and DBC(O2H2O2) =3.9104m2/s. a) Calculate the DAB at 1 atm and 25C(5p). b) Calculate the effective diffusivity of H2 in the O2H2O2 mixture (10p). c) Calculate the total molar fluxes of H2,O2 and H2O2(10p)
