It is thechemical potential for a reaction, and is minimizedat equilibrium. It is defined asG=H-TSwhere H is enthalpy, T is temperature, and Sisentropy.The chemical reaction that causes iron to corrodein air is given by4Fe +302 2Fe2O3in which at 298 K, AH = -1684 kJ andAS-543.7 J/K.AGrxn = 302 kJSubmitPart C✓ CorrectThis positive value for AG means that, at extremely high temperatures, the corrosion reaction will actually greverse, converting iron(III) oxide into iron and oxygen.Teq =Previous AnswersAt what temperature Teq do the forward and reverse corrosion reactions occur in equilibrium?Express your answer as an integer and include the appropriate units.► View Available Hint(s)SubmitProvide FeedbackμÃValueP PearsonUnitsReview | Constants I Periodic Ta?5 of 20Copyright © 2023 Pearson Education Inc.
