What is the Lattice Energy Calculator & How does it work?
Lattice energy is the energy released when an ionic compound is formed from its constituent ions in the gas phase. It is a crucial factor in understanding the stability and properties of ionic compounds.The lattice energy can be estimated using the Born-Haber cycle, which accounts for various processes involved in the formation of an ionic compound. The formula to calculate lattice energy (U) is derived from the electrostatic potential energy between ions:This formula assumes that the ions are point charges and neglects other factors such as polarization effects.
U = -\frac{N_A \cdot z^+ \cdot z^- \cdot e^2}{4 \pi \epsilon_0 \cdot r_0}
var = meaning
NA = Avogadro’s number (6.022 × 1023 mol-1)
z+, z– = charges of the ions
e = elementary charge (1.602 × 10-19 C)
ε0 = permittivity of free space (8.854 × 10-12 F/m)
r0 = equilibrium distance between ions
