Vedclass · Answer

(C) The concentration of Schottky defects in a crystal is given by the formula $n = N \exp(-E/2kT)$,where $n$ is the number of Schottky pairs per $cm^3$,$N$ is the total number of lattice sites per $cm^3$,$E$ is the energy required to form a defect,$k$ is the Boltzmann constant,and $T$ is the temperature.For $NaCl$ at room temperature $(298 \ K)$,the calculated value for the number of Schottky pairs is approximately $10^6$ per $cm^3$.

For $NaCl$,the number of Schottky pairs per $cm^3$ at room temperature is
