3. In a fuel cell, water is produced from oxygen and hydrogen according to the following process: O2 + 2H2 → 2H2O From the information in the table below (all values are given for one mole at 293 K and 1 bar), compute the change in the Gibbs free energy for this process when 1 mole of water is produced. (hint: G = H - TS, and since the temperature is constant in this process, that means that AG = AH - TAS) (the answer is -238 kJ) Substance(form) A, H (kJ) A,G(kJ) S(J/K) Cp (J/K) V (cm) H (9) 0 0 130.68 28.82 0 (9) 0 0 205.14 29.38 HO -285.83 69.91 75.29 18.068 +
