Which of the following is the cell reaction that occurs when the following half-cells are combined?
I2 + 2e– → 2I– (1 M) ; E° = +0.54 V
Br2 + 2e– → 2Br– (1 M) ; E° = +1.09 V
- 2Br– + I2 → Br2 + 2I–
- I2 + Br2 → 2I– + 2Br–
- 2I– + Br2 → I2 + 2Br–
- 2I– + 2Br– → I2 + Br2
Answer
(C) 2I – + Br 2 → I 2 + 2Br –
