What is Lattice energy ?? How to calculate it.
Answers
Answer:
Lattice energy is defined as the energy required to separate a mole of an ionic solid into gaseous ions. Lattice energy cannot be measured empirically, but it can be calculated using electrostatics or estimated using the Born-Haber cycle.
Lattice energy is exothermic. Lattice energy is the energy released when gaseous cations and anions associate with each other to form a solid...
Lattice Energies and Solubility. Lattice Energies and the Strength of the Ionic Bond. The force of attraction between oppositely charged particles is directly proportional to the product of the charges on the two objects (q1 and q2) and inversely proportional to the square of the distance between the objects (r2).
LATTICE ENERGY
★ The lattice energy of a crystalline solid is a measure of the energy released when ions are combined to make a compound.
★It is a measure of the cohesive forces that bind ions.
★ Lattice energy is relevant to many practical properties including solubility, hardness, and volatility.
★ It can be measured by using indirect method that is knoen as born-haber cycle.
