5. The graph below shows the variation in concentration (as fraction of possible defect sites) of vacancies with temperature for copper. (20 points) coordinates: 0.0006, 6.85 Ln(N.Nv) vs 1/T for Vacancies in Copper 0.003 0.005 0.007 0.009 0.011 0.013 0.015 0.017 0019 0.001 -32 -32 82 005 Ln(Nv/N) Natural Log of Fraction of Vacancies - 132 -182 coorcinates: 0.02.-232 -232 1 (Inverse of Temperature in 1l Kelvin) What is the activation energy for the formation of vacancies in copper? Assume that kg = 8.615x10-eV/K. Hints: Remember that fractions of defects follow exponential laws, notice that one axis is in logarithmic scale and the other one is the inverse of temperature.
