The overall reaction for the corrosion of iron (rusting) by oxygen is 4Fe(s) + 302 → 2Fe2O3 (s) a. Calculate AG for the reaction using AG = AH-TAS. (AHºt & Sº values can be found in Appendix G of the OpenStax Textbook) b. Calculate the equilibrium constant using AGº = -RT In K. c. What does this mean for the fate of iron in our environment?
