(a) Plot the diffusion coefficient as a function of inverse temperature (1/T) showing all four diffusion couples in the table.

(b) Recall the temperatures for phase transitions in iron, and for each case, indicate on the graph the temperature range over which the diffusion data is valid.

(c) Why is the activation energy for Fe diffusion higher than that for C diffusion in iron?

(d) Why is the activation energy for diffusion higher in FCC iron when compared to BCC iron?

(e) Does C diffuse faster in FCC Fe than in BCC Fe? Support your answer with a numerical calculation and state any assumptions made.
