Asked by Tim
Free-energy change, ΔG∘, is related to cell potential, E∘, by the equation
ΔG∘=−nFE∘
where n is the number of moles of electrons transferred and F=96,500C/(mol e−) is the Faraday constant. When E∘ is measured in volts, ΔG∘ must be in joules since 1 J=1 C⋅V.
Calculate the standard free-energy change at 25 ∘C for the following reaction:
Mg(s)+Fe2+(aq)→Mg2+(aq)+Fe(s)
Express your answer to three significant figures and include the appropriate units.
I thought it was 373 kj*mol^-1 buts its saying something is wrong

If you will show what you did perhaps we can find the problem. Other than guessing, however, we don't know what you've done.
