Question

Which chemical process is associated with the lattice energy for sodium chloride?

NaCl(g) → Na+(g) + Cl-(g)
NaCl(s) + H2O(l) → Na+(aq) + Cl-(aq)
Na(s) + 1/2 Cl2(g) → NaCl(s)
NaCl(s) → Na+(g) + Cl-(g)

Answer 1

I am absolutely sure thathe chemical process which is associated with the lattice energy for sodium chloride is the last option from the scale represented above - NaCl(s) → Na+(g) + Cl-(g). I choose this one because it has to perform reversed process that must release the same energy.
Do hope you still need the answer because this one is really helpful!
