4. Working with the same equation plot the concentration of vacancies in the same temperature range for activation energies of 1, 2, 5, 10, and 100 eV. Plot all these on the same plot and make each color distinct (have fun and make it look fancy). Also show this as a Log-Log Plot I, = A exp (2) where r, is the number of vacancies, A is a fitting parameter, Qa is the activation energy in eV, k is the Boltzmann constant, and T is temperature.
