This is the 'zero' energy point (or datum line) in the diagram. Well, you can use it to calculate the lattice enthalpy of an ionic solid, or any other. Web online a level chemistry tutor, paul morgan in burnley demonstrates how to calculate the enthalpy of formation of potassium chloride using a born haber cycle. Add the changes in enthalpy to turn one of the elements into its gaseous state, and then do the same for the other element. For the cycle to be useful,. ∆ h° (kj) k (s) → k (g) 89 k (g) → k (g) + e 418 cl 2 (g) → 2 cl (g) 244. You will see that i have arbitrarily decided to. Δhatomisation k = 90 kj/mol w : Ionization energy of k (g) = 425. Step 3 metals exist in nature as single.
Δhatomisation k = 90 kj/mol w : Add the changes in enthalpy to turn one of the elements into its gaseous state, and then do the same for the other element.

Ionization energy of k (g) = 425. Web the born haber cycle below represents the energy changes occurring at 298k when kh is formed from its elementsv : ∆ h° (kj) k (s) → k (g) 89 k (g) → k (g) + e 418 cl 2 (g) → 2 cl (g) 244.
