According to the Born-Haber cycle:
Hoformation
= Hosublimation[Ca(g)]
+ IE1(Ca) + IE2(Ca) + Hosublimation[Br2(g)]
+ Hobond
energy[Br2(g)] + Ea(Br) + Holattice
energy[CaBr2(s)]
i.e. -675 = 178 + 590 + 1145 + 31 + 194 + (-325) + Holattice
energy[CaBr2(s)]
Holattice
energy[CaBr2(s)] = -675 - 178 - 590 - 1145 - 31 -
194 + 325 = -2488 kJ/mol
