Question

The energy change for gaseous ions to convert to a crystalline solid is the “lattice” version of this quantity. For 10 points each:
[10e] Name this thermodynamic quantity, symbolized H, that equals the sum of total energy and pressure times volume.
ANSWER: enthalpy
[10m] Enthalpy can be indirectly calculated according to this law, which states that the change in enthalpy of a reaction is independent of the order of its steps.
ANSWER: Hess’s Law
[10h] Hess’s law underlies a “cycle” named for Fritz Haber and this scientist that is used to calculate lattice enthalpy. This scientist and Oppenheimer name an approximation that involves treating the nucleus’s position as fixed.
ANSWER: Max Born [accept Born-Haber cycle or Born rule]
