The standard reduction potential for Fe^3+ (aq) | Fe (s) electrode is -0.036 V.

Question

The standard reduction potential for Fe^3+ (aq) | Fe (s) electrode is -0.036 V. and for the Fe^2+(aq) | Fe(s) electrode it is -0.4402 v. The standard oxidation potential for the Fe(s) | Fe^2+ half cell is .4402 V (4 dec places). The cell potential for the Fe(s) | Fe^2+(aq)|| Fe^3+ (aq) | Fe(s) is .4042 V (4 dec place). A positive cell potential indicates that the chemical reaction in the cell can be used to generate electrical work. Can this reaction be used to generate work? yes (yes/no). does the potential of the Fe^3+ (aq) | Fe(s) electrode depend on the size of the iron electrode? no (yes/no).

Explanation / Answer

All answer that have done are correct.

Reduction potential = - oxidation potential

SO, Oxidation potential of Fe/Fe2+ = - ( - 4402) = + 4402

Cell potential=Higher reduction potential - lower reduction potential=- 0.036-(- 0.4402)=+0.4042V

Yes electrical energy can be produced.

No potential does not depend on the size of electrode.
