The fraction of vacant lattice sites in a crystal is given by nv/n= exp(-qv/kT) Where, k= Boltzmann constant qv= Energy needed to create a vacancy T= temperature in Kelvin As T increases nv/n too increases.

Where, k= Boltzmann constant
qv= Energy needed to create a vacancy
T= temperature in Kelvin
As T increases nv/n too increases.
See lessThe number of vacancies increases with increase of temperature that is explained with equation with above answer.

See lessThe fraction of vacancies in a crystal is given by n/N= exp(-Q/RT) Where, R= Gas constant Q= Energy required to create a vacancy T= temperature in Kelvin From the formula we can say that vacany concentration exponentially increases with increasing in temperature.
