Born-Haber Cycle is a methodology to analyze the reaction energy, which was introduced by German scientist Born and Firtz Haber. It explains about the formation of ionic compounds, ... Ionization energy is the energy required to remove an electron form a neutral atom or form an ion.

$\huge{\mathbb\blue{ANSWER!!!}}$

BORN-HABER CYCLE.

==> This cycle explains about the lattice energy , when compound is formed..

=> It states that,, more the energy is released or higher the energy is exothermic,, more the LATTICE enthalpy stronger, resulting into the stronger Bond..

=>In a word, this cycle is used to measure the lattice energy of ionic compunds..


For ex==>>

calculate the enthalpy of formation of NaCl

1. known sublimation energy of SODIUM is 108.4 KH/mol

2. Ionisation of SODIUM atom==>> ∆H = 496Kj/mol

3. The dissociation ENTHALPY of the chlorine,,,

i.e, 1/2 Cl2---> Cl

1/2 ∆H = 121 kJ\mol

4. Electron gain ENTHALPY of chlorine atom

Cl + e- ==> Cl
therfore,, ∆eg = - 348.6Kj\mol


5. Formation of NaCl

Na + Cl==> NaCl

apply hess's law..

∆latticeH= 411.2 +108.4+121+496-348.6= + 788kJ...
