Which of the following ionic compounds would be expected to have the highest lattice energy? A)CaBr₂ B)NaBr C)KBr D)RbBr

Question

Quizplus · Accepted Answer

Lattice energy is directly proportional to the charge of the ions and inversely proportional to the size of the ions. CaBr2 has both higher charge (+2 and -1) and smaller ion sizes compared to NaBr, KBr, and RbBr, which makes it have the highest lattice energy.
