Given that

\mathrm{E}_{\mathrm{Fe}^{3+}/\mathrm{Fe}^{2+}}^{\circ}=-0.36 \mathrm{~V}

and

\mathrm{E}_{\mathrm{Fe}^{2+}/\mathrm{Fe}}^{\circ}=-0.439 \mathrm{~V}

respectively. Therefore value of

\mathrm{E}_{\mathrm{F}^{3+}, \mathrm{Fe}^{2+} /\mathrm{Pt}}^{\mathrm{o}}

is:

View answer and explanation

Correct option: D

[3(-0.036)-2(-

0.439)] V

Option D (

[3(-0.036)-2(-

0.439)] V) is correct because it correctly applies the formula for calculating the standard reduction potential of the overall reaction using the given standard reduction potentials and the number of electrons involved.
