Expert Answer
BaS; Ba and S have larger charges.
Since the lattice energy depends upon the charges on the ions and distance between the two.
More the charge on ions more will be lattice enthalpy.
Lesser the distance between ions, smaller the size of ions more will be lattice enthalpy.In BaS , the charge on Ba+2 and S-2 is more as compared to Na+ and Cl- ions in NaCl.
The size of Ba+2 is smaller than Na+ and S-2 is also smaller than the Cl- ions.
