Lattice Energies (E. ) for Common Compounds. Compound. CuI. 958. MgF2. 2908. MgBr2.
Using Born-Haber cycle of MgBr2,Substituting the values, we have, = -524 - 148 - 2187 - 31 - 193 - 2 (-331) = -2421 kJ mol-1Hence lattice enthalpy =

Calculate the lattice energy of Magnesium Sulfide from the data given below.
LiCl NaCl MgCl2 MgF2 MgO CaO F ! q 1 q 2 d 2 The energy to break an ionic bond is the energy required to take the ions in a compound and pull them apart to individual ions. This will be an endothermic process (breaking bonds required energy).
