Using tabulated fH 298 (Table 19.2) and standard molar entropies given in Table 21.2, calculate rxnG 298 for the reaction H2O()H2(g) + 1 2O2(g) a) At what temperature would the reaction become favorable assuming rxnH 298 and rxnS 298 are independent of temperature? b) Using the temperature you found in part (a), and assuming constant pressure, calculate the entropy increase for one mole of a diatomic ideal gas from 298 K. Compare this value (as a percent) to rxnS 298.
