Calculate the value of D at 1768K from the given parameters? (In 10-6 m2/s) Self-diffusion D° = 83mm2/s Q = 283.4 KJ/mol
Calculate the value of D at 1768K from the given parameters? (In 10-6 m2/s) Self-diffusion D° = 83mm2/s Q = 283.4 KJ/mol Correct Answer 0.35
This can be calculated using the equation D° = D*exp (-Q/RT). This equation is similar to that in interstitial diffusion except that the value of activation energy for self-diffusion has an extra term.
