Calculate the lattice energy for PbS using electrostatic forces (assume that it is in a Rock Salt type lattice, although you should be able to determine this). Make sure you use the Born-Mayer correction. Compare the results with the Born-Haber cycle values that you calculate. (All necessary energy values can either be found in your text, at www.webelements.com, or from the following: the 2^nd EA of S = 640 kJ/mol (it should be noted that the 1^st EA of S in this table was listed as a negative value) the ΔH_fº of PbS is -98.3 kJ/mol.
