1. Intrinsic crystal A is fcc and has a vacancy content given by cv = 10 exp(?120/RT), withenergies in kJ/mole. Suppose that a second crystal of A contains 1 at.% of impurity elementB, where the A-vacancy binding energy is 16 kJ/mole with impurities. Assuming ?S = 0 forthe complexes, what is the total vacancy concentration in the impure crystal at 1000K?
