Because a redox potential is just another way of expressing ΔG for a reaction, you can write E for any reaction-even if it is not a redox reaction. For each reaction below:

• Show how to write the complete reaction as a sum of two half-reactions from Appendix H of Harris. [Make sure the electrons in the half-reactions cancel completely-this tells you what value of n to use in subsequent calculations.] Calculate E° from tabulated standard reduction potentials. Calculate ΔG° from E°. Calculate K (at 25 °C), then compare the value you calculated from electrochemical data to the stated literature value (which should be close).

a. Reaction (1) from the Experiment 4 handout. Compare your K to the value given in the handout. I2(aq) + I-(aq) ? I3 -(aq

b. The reaction corresponding to the Ksp of CuI (include physical states throughout). Compare your K to the Ksp listed in Appendix F.
