The free energy change for the following reaction at 25 °C, when [Pb²*] = 1.15 M and [Fe2*]
= 5.40×103 M, is -73.9 kJ:
Pb²*(1.15 M) + Fe(s)→ Pb(s) + Fe²+(5.40×103 M) AG=-73.9 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?
