Calculate lattice energy.

2. The lattice energy of an ionic compound is the energy change when one mole of ionic solid is separated into its gaseous ions. Given the data below, find lattice energy for AlBr3, which is the AH for the following reaction: AlBr3(s) A1+ (g) + 3 Br(g) Chemical reaction Al (s) Al (g) Al (g) Al* (g) + e- Al* (g) Al(g) + e- Al+A1+ (g) + e- Br (g) 2 Br (g) Br (g) + e-Br (g) Al (s) + 3/2 Br (g) AlBr3 (s) AH = ?
