Lattice Enthalpy Of MgCl2

  1. Feb 19, 2010 #1
    can someone please tell me what actually is lattice enthalpy. Is it energy released when one mole of bonds are broken or the energy released when one of an ionic compound is broken into the constituents???? So do we write U or 2U in the born habber cycle of MgCl2????
