###### Question details

Compute diffusion coefficients for the interdiffusion of carbon
in both (a) α-iron (BCC) and (b) γ-iron (FCC) at 850˚C. Assume that
*D*_{0} for the interdiffusion of carbon in α-iron
and in γ-iron are 1.1 × 10^{-6} and 2.3 × 10^{-5}
m^{2}/s, respectively, and that *Q _{d}* are
80 and 148 kJ/mol, respectively.
