NEET Chemistry Cell Reactions MCQ Question
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
Correct Answer
Detailed Explanation
The cell reaction is determined by combining the half-reactions such that the electrons cancel out. The more positive E° value indicates the reduction reaction.
