3.3 Calculate the Q, DS, and DSiso of the following process of 1 kg H2O: H2O(1, -10C,100kPa)H2O(s, -10C,100kPa). Given: At 100 kPa, the melting point of water is 0C, Dfush = 333.3 J/g, cp(H2O,1)= 4.184 Jg-1K-1 and cp(H2O,s) = 2.000 J-g-1K-1 3.4 At 25 oC, standard molar enthalpy of formation of H2O(1) and H2O(g) are -285.830 kJ mol-1 and -241.818 kJ.mol-1; saturated vapor pressure of H2O(1) is 3.166 kPa; standard molar entropy of H2O(1) is 69.91 J.mol-1 K-1. Calculate the standard molar entropy of H2O(g).
