Step 1

(a)

The ionic compound LiBr has cation Li+ and anion Br-. The lattice energy for LiBr is the amount of energy to be supplied to one mole of solid ionic LiBr to break it into its component gaseous ions.

The lattice energy for LiBr can be calculated using the formula given below.

Step 2

(b)

The ionic compound CsBr has cation Cs+ and anion Br-. The lattice energy for CsBr is the amount of energy to be supplied to one mole of solid ionic CsBr to break it into its component gaseous ions.

The lattice energy for CsBr can be calculated using the formula giv...
