Li (g) ––�? Li+ (g) + e�?ΔH = +520kJ/mol F (g) + e�?––�? F�?(g) ΔH = �?28kJ/mol By reversing: F (g) + e�?––�? F�?(g) ΔH = �?28kJ/mol I will get: F+(g) ---------------> F-(g) - e- ΔH = �?28kJ/mol
Writing both reactions again: Li (g) ––�? Li+ (g) + e�?ΔH = +520kJ/mol F-(g) ------> F(g) + e- ΔH = �?28kJ/mol ---------------------------------------------------------------- Li(g) + F-(g)--------->Li +(g) + F(g) ΔH =+192 kJ/mol
