a) In the table below, you can find tabulated diffusion data for certain species. Carbon (C) is an interstitial atom in iron (Fe). Draw "In D" vs "1/T" sketch for the diffusion of C in Fe and -Fe. Clearly show which values you pick from the table to draw this sketch. b) As seen in the table, diffusion of C, a small interstitial atom, in the Fe lattice necessitates less energy than diffusion of the same \( \left.a^{+} ight\urcorner \mathrm{m} \) in the cubic lattice. Please explain why and support your answer with calculations
