This problem is slightly tricky. Calculate E° , ˆ†G° , and K for the reaction.

which is the sum of three half-reactions listed in Appendix H. Use ˆ†G° (= - nFE° ) for each of the half-reactions to find ˆ†G° for the net reaction. Note that, if you reverse the direction of a reaction, you reverse the sign of ˆ†G°.
