Question:
CaO adopts the NaCl-type structure with a = 4.80 Å.
(a) Use the Born–Mayer equation to calculate the lattice-formation energy for CaO.
(b) How well does this estimate agree with the value of −3414 kJ/mol determined from the Born–Haber cycle?
(c) Calculate the size of the repulsive term as a percentage of the attractive term.
(d) Given the fact that SrO has the same structure, would you expect the lattice-formation energy of SrO to be larger or smaller than CaO?
