Compute the number of kilograms of hydrogen that pass per hour through a 5-mm thick sheet of palladium having an area of 0.4 m2 at 500°C. Assume a diffusion coefficient of 1 × 10-8 m2/s, that the concentrations at the high- and low-pressure sides of the plate are 2.4 and 0.6 kg of hydrogen per cubic meter of palladium, and that steady-state conditions have been attained.
compute (a) the interplanar spacing for the set of planes and (b) the atomic radius for the rhodium atom.
