Heat of displacement

  1. 1. Heat of Displacement• Definition: – Energy change when one mole of metal is displaced from its salt solution by a more electropositive metal.• Example iron is displaced from its salt iron(II) sulphate solution by zinc Zn + FeSO4  ZnSO4 + Fe ∆H = -80.6 kJ Ionic equation Zn + Fe2+  Zn2+ + Fe The heat given off when one mole of iron is displaced is 80.6 kJ chem2u
