Question

Lattice energy is Question 4 options: the energy given off when gaseous ions combine to form one mole of an ionic solid the energy required to convert a mole of ionic solid into its constituent ions in the gas phase the energy required to produce one mole of an ionic compound from its constituent elements in their standard states the sum of ionization energies of the components in an ionic solid the sum of electron affinities of the components in an ionic solid

Answer 1

Answer:

Lattice energy is the energy required to convert a mole of ionic solid into its constituent ions in the gas phase

Explanation:

Lattice energy is usually calculated by the Born-Haber cycle, from the affinity energies and sublimation ethalphy values. It is used as an estimation of the ionic energy strength between the ions in an ionic compound.

It is defined as the energy needed to broke 1 mol of a given ionic compound into its ions in the gaseous state. For example, the lattice energy for sodium chloride (NaCl) is the energy required to separate 1 mol of solid ionic compound (NaCl(s)) and produce the sodium and chlorine ions in the gas phase: Na⁺(g) and Cl⁻(g).
