Hydrogen purification was conducted at 550 °C using a 3-mm-thick palladium sheet having an area of 0.25 m?. (a) Calculate the diffusion coefficient of hydrogen in palladium at this temperature. The preexponent and the activation energy are 12,000 J/mol and 6.5 x 108 m?/s, respectively. R = 8.3145 J/mol-K. (b) When the steady-state condition was attained, hydrogen concentrations at the high- and low-pressures side of the plate were 1.7 and 0.5 kg/m³. Compute the amount of hydrogen that passes through the sheet per hour (in kg/h).
