Predict the Relationship Between the Lattice Energies (U) of KBr

question 92

Multiple Choice

Predict the relationship between the lattice energies (U) of KBr and CaO.

• A) U_CaO > 4 U_KBr because the ionic charges are +2 and -2 and the distance between the ions is smaller.
• B) U_CaO < 4 U_KBr because the ionic charges are +2 and -2 and the distance between the ions is larger.
• C) U_CaO > 2 U_KBr because the ionic charges are +2 and -2 and the distance between the ions is smaller.
• D) U_CaO < 4 U_KBr because the ionic charges are +2 and -2 and the distance between the ions is larger..
• E) U_CaO and U_KBr are about the same because the larger ionic charge is compensated by the larger distance between the ions.
