FAQ on Lattice Energy
Q1: What is Lattice Energy?
Answer:
The lattice energy is defined as the energy required by the ionic compound in the crystal lattice to change to the gaseous state. It is measured in kJ/mol.
Q2: What are the Factors on Lattice Energy depends?
Answer:
Lattice energy depends on various factors such as,
- Charge on the Constituent Ions
- Distance between the Ions
Q3: How charge of an Ion affect Lattice Energy?
Answer:
The charge on the ions is directly proportional to the lattice energy of the crystal and the higher is the charge on the ion the higher the lattice energy of the crystal, i.e. the higher energy is required to break the ionic compound from its crystal form to gaseous form.
Q4: How temperature affects Lattice Energy?
Answer:
There is no subsequent effect of the temperature on the lattice energy of the crystal, but the temperature effect the lattice enthalpy of the crystal at higher temperature enthalpy of the particle decreases.
Q5: What is Hess law?
Answer:
Hess law is the basic law that tells us that the total change in the enthalpy of a chemical reaction remains constant irrespective of the path taken by the reaction.
Lattice Energy
Lattice Energy is the energy required to break apart an ionic compound into its gaseous ions. We can also define it as the energy released when the gaseous atoms combine to form a crystal lattice. The lattice energy of any compound cannot be directly measured and we use various methods or techniques to find the lattice energy such as the use of the Born Haber cycle to find the lattice energy of any compound. Lattice energy is measured in kJ/mol.
In this article, we will learn about Lattice energy, lattice enthalpy, their difference, and others in detail.
