Calculate the fraction of atom sites that are vacant for copper (cu) at its melting temperature of 1084°c (1357 k). assume an energy

Calculate the fraction of atom sites that are vacant for copper (cu) at its melting temperature of 1084°c (1357 k). assume an energy for vacancy formation of 0.90 ev/atom. (b) repeat this calculation at room temperature (298 k). (c) what is ratio of nv /n(1357 k) and nv /n(298 k)?

Answer

We know , vacancy concentration is given by : Calculate Here , . ( Boltzmann’s constant ) Calculate T = Absolute temperature in Kelvin . Now , Calculate Hence , this is the required solution .
