New cards
Hess’s law
The total enthalpy change of a reaction is always the same, no matter which route is taken.
2
New cards
what is working out the theoretical lattice enthalpy
doing calculations based on the purely ionic model of a lattice.
3
New cards
What does the purely ionic model of a lattice assume?
Assumes that all the ions are spherical, and have their charge evenly districuted among them.
