In a materials science video I was watching today the prof. said we could use the arrhenius equation to estimate the number of vacancy point defects in a material. And gave the following equation:
Nv = N exp(-Qv / KBT)
Where Nv = number of vacancies
N= # of atom sites
Qv = energy of vacancy formation
KB = Boltzmann constant
T = Temp
I don't understand how we got to that equation from the Arrhenius equation. How do the two relate? How is the above equation derived from the Arrhenius equation?
