Theoretical And Experimental Enthalpy Flashcards
1
Q
The purely ionic model of a lattice
A
Assumes that all ions are spherical and have their charge evenly distributed around them
2
Q
Experimental value is different because
A
It has covalent characteristics, the positive ion polarises the negative ion
More polarisation = more covalent character
3
Q
Comparing lattice enthalpy example explanation
A
Difference in values bigger in mag than na showing the bonding is STRONGER than so bonds are polarised and have a lot of Cov character
