Ionic Lattice Energy

APCHEM-NLYGUI

The lattice energy of four ionic compounds, W, X, Y, and Z, are measured. The energies are found to be -922 kJ/mol, -769 kJ/mol, -718 kJ/mol, and -688 kJ/mol, respectively.

The four ionic compounds are $NaCl$, $NaF$, $KBr$, and $KCl$.

Which of the following ionic compounds could be identified as Compound X, based on the lattice energy?

A

$NaCl$

B

$NaF$

C

$KBr$

D

$KCl$
