The free energy change for the following reaction at 25 °C, when [Cr³+] = 7.70x10-3 M and [Cu2+] = 1.12 M, is 66.7 kJ: Cr³+(7.70x10-3 M) + Cu+ (aq) Cr²+ (aq) + Cu²+(1.12 M) AG = 66.7 kJ What is the cell potential for the reaction as written under these conditions? Answer: →>> V Would this reaction be spontaneous in the forward or the reverse direction?
