the electron affinity for I is The lattice energy of potassium bromide is more exothermic than the lattice energy of rubidium iodide because lattice energy is inversely proportional to atomic radius. Lattice energy (calculated) [kJ/mol] Lattice energy (measured in Born-Haber-Fajan cycle) [kJ/mol] (CH3CH2CH2CH2)4NHCl2. 290. The lattice energy of potassium iodide is the energy required for the following reaction. KI (s) → K+ (g) + I− (g) ΔHrxn = ΔHlattice Use the Born-Haber cycle to calculate ΔHlattice for KI (s) from the information given below. Equation 1: 2 K (s) + I2 (g) → 2 KI (s) ΔH1 = −655 kJ/mol Equation 2: K (s) → K (g) ΔH2 = 89 kJ/mol Equation 3: I2 (g) → 2 I ABOUT LATTICE.

The lattice energy of LiF is 1023 kJ/mol, and the Li–F distance is 201 pm. MgO crystallizes in the same structure as LiF but with a Mg–O distance of 205 pm.

It can also be defined as the amount of energy that is spent to separate an ionic crystal into its constituent ions. It can be evaluated considering different contributions to the potential energy. Lattice Energy. 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. MaLb (s) a Mb+ (g) + b Xa- (g) U kJ/mol. This quantity cannot be experimentally determined directly, but it can be estimated using Hess Law in the form of Born-Haber cycle.

Alternatively, lattice energy can be thought of as the energy required to separate a mole of an ionic solid into the gaseous form of its ions (that is, the reverse of the reaction shown above). NaCl Crystalline Lattice Sodium ions (Na + ) and chloride(Cl – ) ions, depicted in purple and green respectively, alternate in the crystal lattice of solid NaCl. The lattice energy of an ionic compound is the enthalpy change which occurs when one mole of an ionic compound dissociates into its ions in gaseous state. More ionic is a compound, stronger would be the ionic bond and more would be the lattice enthalpy ( Ref ). The lattice energy of CsF is -744 kJ/mol, whereas that of BaO is -3029 kJ/mol.

The overall potential energy of a chemical compound is also named as the lattice energy and it can be defined in terms of electrostatic or repulsive energy. The distance between ions is greater in "KI", so "KI" should have a lower lattice energy and a lower melting point than "NaBr". A simple extrapolation from "NaCl" through "NaBr" suggests that "KI" should have a lattice energy of about 680 kJ/mol and a melting point of about 700 °C. The actual values are 698 kJ/mol and 681 °C.
