Lattice energy is inversely proportional the distance between two ions in a ionic compound,therefore the Compound with the smaller lattice energy wii have the larger distance between two ions.
Given NaCl, and KF , the one with smaller lattice energy is KF.
Therefore , of the two , the one which has larger distance between the atoms is KF.
Hint: Lattice energy is inversely proportional to size and directly proportional to charge of ions.
Bivalent-Bivalent> bivalBivalent-Monovalent> Monovalent-Monovalent

The total potential energy describing the NaCl lattice is given by: Utot = [ ( -(αe^2) / (4πε 0r) ) + ( A / r^8 ) ], where a is the Madelung constant (a=1.75 for NaCl) and A is a positive constant. 1. What is the physical meaning of the two terms of Utot? Let r0 be the value of the ionic separation r for which Utot is minimum. 2. Deduce an expression of A as a function of r0....
