Question

Identify the steps that are expected to be exothermic in the Born–Haber cycle for the formation of MgBr₂.

Accepted Answer

Br(g) + e^-(g) → Br^- and Mg²⁺(g) + 2 Br^-(g) → MgBr₂(s)

Answer

Br(g) + e^-(g) → Br^- and Br₂(g) → 2 Br(g)

Answer

Br₂(g) → 2 Br(g) and Mg²⁺(g) + 2 Br^-(g) → MgBr₂(s)

Answer

Br(g) + e^-(g) → Br^- and Br₂(l) → Br₂(g)

Answer

Br₂(l) → Br₂(g) and Mg(g) → Mg²⁺(g) + 2 e^-
