Problem Details

Use the following information to calculate the ΔH° lattice of MgF2:

Mg(s) → Mg(g)                     ΔH° =148 kJ

F2(g) → 2F(g)                       ΔH° =159 kJ

Mg(g) → Mg(g)+e-              ΔH° =738 kJ

Mg+(g) → Mg2+ (g)+e-          ΔH° =1450 kJ

F(g)+e- → F-(g)                     ΔH° =-328 kJ

Mg(s) +F2(g) → MgF2 (s)      ΔH° =-1123 kJ
