What is lattice enthalpy of formation? |
Enth change when 1mlc of solid ionic compound is formed f gaseous ions under standard conditions |
|
|
What is lattice enth of dissociation ? |
Enth change when 1mlc of solid ionic compound is completely dissociated into its gaseous ions under standard conditions |
|
|
What are theoretical lattice enth? |
Based on purely ionic model of a lattice (assume spherical shape) |
|
|
What is found with experimental lattice enth? Why? |
The value is different to theoretical because most ionic compounds have some covalent character (a bit stretched rather than spherical) |
