Consider the following cell reaction at 25C.
2Cr(s) + 3Fe2+(aq) → 2Cr3 + (aq) + 3Fe(s)
Calculate the standard cell potential of this cell from the standard electrode potentials, and from this obtain ∆Go for the cell reaction. Use data in Appendix C to calculate ∆Ho; note that Cr(H2O)63+(aq) equals Cr3+(aq). Use these values of
∆Ho and
∆Go to obtain
∆So for the cell reaction.
