The overall reaction and equilibrium constant value for a hydrogen-oxygen fuel cell at 298 K is 2 Hz(9) + O2(g) + 2 H2O(1) K = 1.28 x 10% (a) Calculate E and AG at 298 K for the fuel-cell reaction. E = AG = kJ (b) Predict the signs of AH and AS for the fuel-cell reaction. Ο ΔΗ' <0. ΔS" <0 O AH° <0, AS > 0 Ο ΔΗ' > 0, ΔS" <0 ΔΗ" > 0, ΔS > 0 AH <0, the sign of AS cannot be predicted OAH > 0, the sign of AS cannot be predicted (C) As temperature increases, does the maximum amount of work obtained from the fuel-cell reaction increase, deu increases decreases remains the same
