Question

Identify the steps that are expected to be exothermic in the Born–Haber cycle for the formation of MgBr_{2}.

Accepted Answer

Br(g) + $$e^{-}(g$$) → $$Br^{-}$$ and $$Mg^{2+}(g) + 2$$ $$Br^{-}(g$$) → MgBr_{2}(s)

Answer

Br(g) + $$e^{-}(g$$) → $$Br^{-}$$ and Br_{2}(g) → 2 Br(g)

Answer

Br_{2}(g) → 2 Br(g) and $$Mg^{2+}(g) + 2$$ $$Br^{-}(g$$) → MgBr_{2}(s)

Answer

Br(g) + $$e^{-}(g$$) → $$Br^{-}$$ and Br_{2}(l) → Br_{2}(g)

Answer

Br_{2}(l) → Br_{2}(g) and Mg(g) →  $$Mg^{2+}(g) + 2$$ $$e^{-}$$
