How to determine highest lattice energy
WebSep 26, 2024 · The Lattice energy, U, is the amount of energy required to separate a mole of the solid (s) into a gas (g) of its ions. (1) M a L b ( s) → a M b + ( g) + b X a − ( g) This quantity cannot be experimentally determined directly, but it can be estimated using a … There are other factors to consider for the evaluation of lattice energy and the tre… WebLattice energy depends on the strength of interactions between cations and anions in the lattice, which we can estimate using Coulomb's law: Fₑ = (q₁q₂)/r². According to this …

WebAug 11, 2014 · The equation is F = − k ⋅ q 1 ⋅ q 2 r 2 k is a constant; q 1 and q 2 are the charges on the ions and r is the distance between the ions. So the larger the charge the greater the force, and the smaller the radius the smaller the distance between the ions (smaller r in the equation) again leading to a stronger force.
