A 0.001 in. BCC iron foil is used to sepa- rate a high hydrogen content gas from a low hydrogen content gas at 650°C. 5 × 108 H atoms/cm³ are in equilibrium on one side of the foil, and 2 × 10³ H atoms/cm³ are in equilibrium on the other side. Determine (a) the concentration gradient of hydro- gen; and (b) the flux of hydrogen through the foil.

A 0.001 in. BCC iron foil is used to sepa-
rate a high hydrogen content gas from a
low hydrogen content gas at 650°C. 5 × 10%
H atoms/cm³ are in equilibrium on one side
of the foil, and 2 × 10³ H atoms/cm³ are in
equilibrium on the other side. Determine
(a) the concentration gradient of hydro-
gen; and
(b) the flux of hydrogen through the foil.
