Consider the standard reduction potentials (in volts) as shown in figure. Find E°.
|
0.326 V 0.425 V 0.756 V 0.512 V |
0.756 V |
The correct answer is option 3. 0.756 V. The reaction scheme is
This can be broken down into
We know, \(nE^0 = n_1E_1^0 + n_2E_2^0\) \(E^0 = \frac{−2 × 0.936 − 2 × 0.576}{4}\) or, \(E^0 = −0.756 V\) |
