The lattice energy for an ionic compound cannot be measured directly but can be calculated from the Born- cycle, using a series of individual steps for which all enthalpies are known except for the lattice energy. This method is an application of Hess's law which, states that the overall energy change for a process is given by the of the enthalpy changes for the individual steps.
