Hello Champions. Before drawing the Bond Haber Diagram, please recall enthalpy formation, enthalpy atomisation, ionisation energy, electron affinity, lattice energy and bond energy.
- Enthalpy of Formation is the heat changed when 1 mole of a compound is formed from its elements in their most stable state.
- Enthalpy atomisation is the heat absorbed when 1 mole of gaseous atoms is formed from its element in its most stable state at stated temperature and pressure
- Lattice energy is the energy released when one mole of a solid ionic compound is formed from its gaseous ions.
- First ionisation energy is the minimum energy required to remove an electron from a neutral gaseous atom in its ground state.
- Electron affinity the amount of energy change to added 1 mole of electron into 1 mole of gaseous atoms or ions in their ground state.
- Bond energy is the energy required to break a chemical bond.
