4) The expression U + PV naturally arises in thermodynamics and is called the enthalpy, H; thus, H = U + PV. The entire expression U – TS + PV, which was shown to naturally develop by this argument, is called the Gibbs free energy, G:* thus, G = U + PV – TS = H – TS. 6) This is true for a reversible process (essentially at equilibrium) carried out at constant T and P. Therefore, under these conditions, the maximum work over and above that associated with the volume change is given by the decrease in the Gibbs free energy (GFE).
3 along with their standard equilibrium half-cell potentials. For any specific pure metal, the physical state or condition may also influence the tendency for the metal to become anodic and corrode. 3 Anodic reactions and equilibrium potentials Examples of anodic reactions Zn = Zn2+ + 2e Fe = Fe2+ + 2e Pb = Pb2+ + 2e Cu = Cu2+ + 2e Ag = Ag+ + e Standard equilibrium half-cell potentials(a), Eo (mV vs. SHE) –763 –440 –126 +342 +799 (a) These standard values correspond to 25 °C and unit activity of the metal ions and would need to be corrected for the actual temperature and activity to determine E′.
In calculating corrosion rates, the anodic current density should be evaluated as ia = Icorr / Aa. Why? 7. Relative to question 6, give another reason why current density is fundamentally more important than current. 8. In a corroding system involving distinguishable anodic and cathodic areas, which is more desirable, (a) a large Aa/Ac area ratio or (b) a small Aa/Ac area ratio? Explain. ′ must 9. 18, for corrosion to occur, Icorr must be positive, or E X ′ . 3)? Assume standard conditions such that E′ = Eo.
