The Eo values for the following two half-reactions are listed in an ancient standard reduction potential table as, respectively, 0.907 and 0.972 volts.
2 Hg2+ + 2 e- Hg22+
NO3- + 4 H+ + 3 e- NO(g) + 2 H2O(l)
When properly combined to form an electrolytic cell, the standard free energy change (kJ) which would be calculated for the cell reaction using these ancient values is:
