P3E.1 (a) By integrating the Gibbs-Helmholtz equation between temperature T, and T, and with the assumption that AH is independent of temperature, show that AG(T,) _ AG(T,) T, T, 2+aH() (부-구 where AG(T) is the change in Gibbs energy at temperature T. (b) Using values of the standard Gibbs energies and enthalpies of formation from the Resource section, determine A,G° and A,H® at 298 K for the reaction 2 CO(g) + 0,(g) → 2 CO,(g). (c) Hence estimate A,G° at 375 K.
