The Correct Option is C
Solution and Explanation
The reduction of MnO$_4^-$ to MnO$_2$ involves a change in the oxidation state of Mn from +7 to +2.
According to the balanced redox reaction, the number of electrons required to reduce 1 mole of MnO$_4^-$ is 5.
Thus, the total charge required for the reduction is 5 Faradays (F).
Hence, the correct option is (3) 5 F.

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:
\( E^\circ_{\text{Sn}^{4+}/\text{Sn}^{2+}} = +0.15V \)
