Question:

Calculate the standard free energy change for the reaction2Fe+ (aq) + 21-(aq)  2Fe+ (aq) + I(s)

Strategy Use Table 18.1 to determine the cell potential; then use Equation 18.2 to calculate the ΔG°. You will also have to determine the number of moles of electrons, n, that are transferred in this reaction.

Equation 18.2AG = nFE
