C3. Given that Do = 124 mm2/s and the activation energy for self-diffusion is 413.3 kJ/mol for Ta (BCC), which melts at 3269 K, a) Calculate the self-diffusion coefficient (Dra) at 300 °C. b) Given a jump distance of 0.28 nm, calculate its jump frequency. Show units, if applicable. c) Assuming the jump distance is unchanged, calculate the jump frequency if the crystal structure was FCC instead.
