The purification of hydrogen gas by diffusion through a palladium sheet was discussed in section 5.3 .compute the number of kilograms of hydrogen that pass per hour through a 6-mm-thick sheet of palladium having an area of 0.25 mm^2 at 600 c.Assume a diffusion coefficient at the high- and low –pressure sides of the plate are 2.0 and 0.4 kg of hydrogen per cubic meter of palladium, and that steady-state condition have been attained
