For this problem, we are asked to list the individual steps used in constructing a Born - Haber cycle for the formation of BaI2 from the elements. 

Also to determine which of the steps would we expect to be exothermic, and to write the chemical equation for the second step of a Born - Haber cycle.


The Born-Haber Cycle is a thermochemical tool used to analyze the contributing factors that affect the stability of an ionic compound.

  • Hess's Law states that the overall change in energy of a process can be determined by breaking the process down into steps, then adding the changes in the energy of each step. The Born-Haber cycle is essentially Hess's Law applied to an ionic solid.

Recall that:

Endothermic Processes are:

  • Bond breaking
  • Removal or loss of electron/s
  • Fusion, vaporization, sublimation

Exothermic Processes are:

  • Bond formation
  • Gaining or addition of electron/s
  • Freezing, condensation, deposition


Under the Born-Haber Cycle, the formation of an ionic solid is the result of a metal and a gaseous nonmetal combining together.
