CBSE Class 11-science Answered
which of the following two compounds would you expect to have a higher lattice energy value-KCL or NaCl?

Expert Answer
Lattice energy depends on the magnitude of the charges of the ions and the distance between them.
Comparing NaCl and KCl, we see that the lattice energies are: 788, 699 kJ/mol, respectively.
Since the anion is the same for all three salts and the cations are all +1, the only difference between these has to be in the distance between the ions.
