The shape of the graph Δ mix H m o = f( x Co ) obtained in the region 1528 K < T < 1765 K confirms the existence of a liquid miscibility gap. A new position of the miscibility gap and the liquidus line on the In-rich side of the phase diagram is proposed: the coordinates of...
The arrow pointing down from this to the lower thick line represents the enthalpy change of formation of sodium chloride. The Born-Haber cycle now imagines this formation of sodium chloride as happening in a whole set of small changes, most of which we know the enthalpy changes for - except,...

resulting in an unfavorable change in enthalpy. At the same time, the formation of enthalpic van der Waals interactions, as well as the hydrophobic effect (see Glossary), ensure that this process is favorable. (4) Eventually, the ligand reaches a binding conformation and a significant favorable...
An enthalpy change is approximately equal to the difference between the energy used to break bonds in a chemical reaction and the energy gained by the formation
