🤓 Based on our data, we think this question is relevant for Professor Kammerdiener's class at KSU.
Use the Ionic Bond Energy (Lattice Energy) Equation to estimate which of the compounds would have the highest or lowest lattice energy.
The lattice energies of FeCl3, FeCl2, and Fe2O3 are (in no particular order) -2631, -5359, and -14,774 kJ/mol. Match the appropriate formula to each lattice energy. Explain.
