WebOct 4, 2024 · The simplified form of Coulomb’s law is used to calculate the lattice energy of ionic compounds. U = − k Q 1 Q 2 r. In this formula, U depicts the lattice energy of the ionic compound. Q 1 and Q 2 are the positive and negative ions of the compound. r represents the internuclear distance of the ions. And k is the proportionality constant. Webc. H2C=C=CH2 d. H2C=CH2 e.

WebFor example, the bond energy of the pure covalent H–H bond, D H–H, is 436 kJ per mole of H–H bonds broken: H 2 ( g) 2 H ( g) D H−H = Δ H ° = 436 kJ. Molecules with three or more atoms have two or more bonds. The sum of all bond energies in such a molecule is equal to the standard enthalpy change for the endothermic reaction that ... WebTo decide whether BaS or CaO has the greater lattice energy, we need to consider the relative sizes of the ions because both compounds contain a +2 metal ion and a −2 chalcogenide ion.
