The free energy change for the following reaction at 25 °C, when [Fe2*] = 1.66x10-3 M and [Cr*]= 1.15 M, is 22.0 kJ: Fe2+(1.66x10-3 M) + 2Cr2*(aq)–→Fe(s) + 2Cr*(1.15 M) AG = 22.0 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?
