On the basis of the following E° values, the strongest oxidizing agent is: [ Fe ( CN )_6]^4- →[ Fe ( CN )_6]^3-+ e^-1; E^°=-0.35 V; Fe^2+ → Fe^3++…

On the basis of the following E° values, the strongest oxidizing agent is : $$\begin{array}{ll} {\left[\mathrm{Fe}(\mathrm{CN})_6\right]^{4-} \rightarrow\left[\mathrm{Fe}(\mathrm{CN})_6\right]^{3-}+\mathrm{e}^{-1} ; \mathrm{E}^{\circ}=-0.35 \mathrm{~V}} \\ \mathrm{Fe}^{2+} \rightarrow \mathrm{Fe}^{3+}+\mathrm{e}^{-1} ; & \mathrm{E}^{\circ}=-0.77 \mathrm{~V} \end{array} $$
