Construct the Born-Haber cycle for AB, where A is a divalent cation, and B is a divalent anion. The formation of AB starts with A(s) and B2(g). You do not have to use numeric values, just write the discrete steps, and label each with an energy term such as ionization energy (I), or electron affinity (Ea), formation enthalpy (ΔHf), sublimation enthalpy (ΔHs), or bond enthalpy (D0), etc. Be sure to clearly indicate the signs (+ or -) of each term....
Find the experimental lattice energy of Magnesium Chloride (MgCl2) using a Born-Haber cycle. Draw the Born-Haber cycle and indicate the involved steps of the cycle. Label the cycle carefully. Some information that might be useful. Electron affinity of Cl:EA1 = -348.6kJ/mol, EA2 = +750kJ/mol.
