Use the following to calculate AHntice of NaCl:
Na(s)
AH° =
Na(g)
2CI(g)
Na*(g) + e-
CI (g)
109 kJ
AH° = 243 kJ
Cl2(8)
Na(8)
CI(g) + e-
Na(s) + Cl2(8) NaCI(s)
Compared with the lattice energy of LiF (1050 kJ/mol), is the
magnitude of the value for NaCl what you expected? Explain.
ΔΗ-
496 kJ
AH° = -349 kJ
AH° = -411 kJ
