Finding lattice energy of compounds
WebFeb 24, 2024 · So the bond association enthalpy for ionic compounds like $\ce{NaCl}$ and $\ce{NaBr}$ can be easily calculated from a Born-Haber cycle. But the way a Born-Haber cycle is constructed it uses info that only really applies to mono-atomic ions like $\ce{Cl^-}$. ... .$ The lattice energy is obtained through the relation: ... WebThe lattice energy is the total potential energy of the crystal. The lattice energy is usually given in kilojules per mole (kJ/mol). The science, which deals with crystals properties is crystallography. There are theroretical models, which allow to calculate (with better or worse result) the lattice energy.

WebThe addition of enthalpy to an electron can be explained as the amount of energy exerted when an atom gains an electron, hence greater the electron affinity, the larger will be the lattice energy. Formula ΔU = ΔH - pΔVm Where , ΔU = lattice energy of the mole ΔH = lattice enthalpy of the mole ΔVm = change of volume per mole P = outer pressure WebHard Sphere: Born-Landé: Born-Mayer: Kapustinskii: Choose the cation, anion and structure type from the lists provided or choose your own values for the ion charges and radii, the structure type and the value of n. Press "calculate" to work out the different ionic lattice energies and "reset" to clear all entries.
