Lattice energy is the energy needed to break the solid apart
into its ions in gaseus state or
When oppositely charged particles come toghether and forms a
salt and gives out energy that is lattice energy
So if we want to show the lattice energy change then reactioon
should be.
Ca2+ (g) + 2 F- (g) —- > CaF2 (s)
Or
CaF2 (s) —- > Ca2+ (g) + 2F- (g)
But there is no any reaction like these so answer is E. non of
these choices is correct.
