Born-Haber Cycle and Related Concepts

The video tutorial explains the Bourne Harbor Cycle, a method to calculate lattice enthalpy using Hess's Law. It defines lattice enthalpy as the energy needed to break an ionic lattice into gaseous ions, emphasizing its endothermic nature. The tutorial introduces the FAIL technique to remember the cycle's steps: Formation, Atomization, Ionization, and Lattice enthalpy. It details each step, including the use of data book values for atomization and electron affinity. The video concludes with a summary of how to calculate lattice enthalpy using the cycle.

What is the primary purpose of the Born-Haber Cycle?

• To measure the temperature change in a chemical reaction.

• To determine the lattice enthalpy of an ionic compound.

• To calculate the energy required to form a covalent bond.

• To find the molecular weight of a compound.

How is lattice enthalpy defined in IB Chemistry?

• The energy needed to form a covalent bond.

• The energy change when a solid dissolves in water.

• The energy required to break an ionic lattice into gaseous ions.
