A mixture of H2 and D2 is contained in two bulbs connected by a porous plug. The bulbs are maintained at different temperatures of 200 and 600 K. The thermal diffusion parameter kT = 0.0166. The mole fraction of deuterium is initially equal to 0.1. Find the differences in the mole fractions in the two bulbs when a steady state is established due to the combined effect of Fick and thermal diffusion. In which bulb does hydrogen accumulate?
