1. Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the
lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle
to obtain the value of lattice energy for PbS. You will need the following data following data:
AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol;
S¯(g)
(g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903.
Remember that enthalpies of formation are calculated beginning with the elements in their
standard states (S8 for sulfur). The formation of S2, AHF: S2 (g) = 535 kJ/mol.
Compare the two values, and explain the difference.
