Which species is the strongest oxidizing agent based on the given standard electrode potentials?
| \(E^{\ominus} values : \) | \(\left(Fe\right)^{3 +} / \left(Fe\right)^{2 +} = + 0 . 77 V\) |
| \(I_{2} (s)/ I^{-} = + 0 . 54 V\) | |
| \(\left(Cu\right)^{2 +} / Cu = + 0 . 34 V\) | |
| \(\left(Ag\right)^{+} / Ag = +0 . 80 V\) |
1. Fe3+
2. I2(s)
3. Cu2+
4. Ag+
Using the standard electrode potential, find out the pair between which redox reaction is not feasible.
\(\begin{aligned} & \mathrm{E}^{\ominus} \text { values: } \mathrm{Fe}^{3+} / \mathrm{Fe}^{2+}=+0.77 ; \quad \mathrm{I}_2 / \mathrm{I}^{-}=+0.54 ; \\ & \mathrm{Cu}^{2+} / \mathrm{Cu}=+0.34 ; \mathrm{Ag}^{+} / \mathrm{Ag}=+0.80 \mathrm{~V} \end{aligned}\)
| 1. | Fe3+ and I- | 2. | Ag+ and Cu |
| 3. | Fe3+ and Cu | 4. | Ag and Fe3+ |
