Question

Calculate the number of Frenkel defects per cubic meter in silver chloride at 350°C. The energy for defect formation is 1.1 eV, whereas the density for AgCl is 5.50 g/cm' at 350°C.

Answer 1

To calculate the number of Frenkel defects per cubic meter in silver chloride at 350°C, we use the formula N = (Nexp * exp(-Q/kT))/V where Nexp is the number of defects per mole, Q is the energy for defect formation, k is the Boltzmann constant, T is the temperature in Kelvin, and V is the molar volume. We can then substitute the given values and calculate the answer.

Step-by-step explanation:

To calculate the number of Frenkel defects per cubic meter in silver chloride at 350°C, we need to use the formula:

Frenkel Defects per cubic meter = (Nexp * exp(-Q/kT))/V

Where Nexp is the number of defects per mole, Q is the energy for defect formation, k is the Boltzmann constant, T is the temperature in Kelvin, and V is the molar volume.

In this case, we are given the energy for defect formation as 1.1 eV and the density of AgCl at 350°C as 5.50 g/cm³. We can convert the energy to Joules using the conversion factor 1 eV = 1.602176634 × 10^-19 J and the density to kg/m³ by multiplying by 1000. Substituting the values into the formula, we can calculate the number of Frenkel defects per cubic meter.
