Solution and Explanation
The standard electrode potentials are given as:
\[
E^\circ_{Fe^{3+}/Fe^{2+}} = 0.771 \, \text{V}, \quad E^\circ_{Br_2/Br^-} = 1.09 \, \text{V}.
\]
Since the reduction potential of \( Br_2/Br^- \) is higher than \( Fe^{3+}/Fe^{2+} \), bromide ions cannot be oxidized by ferric ions.

Standard electrode potential for \( \text{Sn}^{4+}/\text{Sn}^{2+} \) couple is +0.15 V and that for the \( \text{Cr}^{3+}/\text{Cr} \) couple is -0.74 V. The two couples in their standard states are connected to make a cell. The cell potential will be:
To calculate the cell potential (\( E^\circ_{\text{cell}} \)), we use the standard electrode potentials of the given redox couples.
Given data:
\( E^\circ_{\text{Sn}^{4+}/\text{Sn}^{2+}} = +0.15V \)
\( E^\circ_{\text{Cr}^{3+}/\text{Cr}} = -0.74V \)- CBSE CLASS XII - 2025
