WitrynaLe cycle de Born-Haber. Nous traiterons l'exemple classique du chlorure de sodium. La réaction où l'énergie réticulaire est mise en jeu est la suivante : Pour déterminer sa valeur, on réalise un cycle se basant sur la réaction correspondant à l'énergie interne standard de formation : - 2 Er = - 2 E I (Na) - 2 D sublim U° (Na) - 2 A E ...

5.1.4 Calculations using Born-Haber Cycles - Save My Exams
WitrynaSome Born-Haber cycles will require multiples of the relevant energy change, e.g. if forming CaCl 2, then you'll need 2xΔ EAH to turn two 2Cl (g) into 2Cl-(g) in order to … WitrynaThe scheme below represents Born-Haber cycle for BaO crystal. Step 1. Sublimation of solid Ba: Ba(s) → Ba(g), ΔH1 = 180.0 kJ/mol During this process, the change in enthalpy is positive, energy is required to change the state of barium from solid to gaseous (to break metal lattice).
