4.1.2: Born-Haber Cycles Flashcards
1
Q
Hess’s law
A
The total enthalpy change of a reaction is always the same, no matter which route is taken.
2
Q
Purely ionic model assumes that
A
all ions are spherical and have their charge evenly distributed around them.
3
Q
Evidence that ionic compounds usually have some covalent character
A
experimental lattice enthalpy from the Born-Haber cycle is usually different to theoretical enthalpies
4
Q
If the theoretical and experimental enthalpies for a compound are very similar…
A
it has very little covalent character
5
Q
If the theoretical and experimental enthalpies for a compound are very different…
A
it has lots of covalent character
