Vedclass · Answer

(A) The Schottky defect is a type of point defect in ionic crystals where an equal number of cations and anions are missing from their lattice sites.This defect is temperature-dependent because the number of vacancies increases with an increase in temperature.As the temperature increases,the thermal energy of the ions increases,making it easier for them to leave their lattice sites.Therefore,the Schottky defect is maximum at the highest temperature among the given options.Comparing the temperatures: $18\,^oC = 291\, K$,$273\, K$,$283\, K$,and $-273\,^oC = 0\, K$.The highest temperature is $291\, K$ $(18\,^oC)$.

At what temperature will the Schottky defect be maximum?
