Consider the standard reduction potentials (in volts) as shown in figure. Find E°.
Answer & explanation
Correct answer: option 3
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, \(E^0 = −0.756 V\)
