The bulk phase is separated from a catalytic surface by a distance of 1 mm. The following reaction occurs at the catalytic surface, z=1mm.

A+2BC

At z=0, the molar fraction of A is x_A0=0.2. The pressure is 4 atm and T = 520K.

1.Find the total concentration C; the pressure and temperature remain constant.

2. Use the Stefan Maxwell equations to solve for x_A and x_C as a function of z. Assume the reaction is fast and x_A=x_B=0,z=1mm. Assume all the diffusion coefficients are 10^-5 m²/s.

3. Find x_C0, that is x_C at z=0.
