Homework Answers
Reaction for the condensation: H2O(g) <----> H2O(l)
ΔCp = (Cp)H2O(l) - (Cp)H2O(g) = 75.3 - 35.9 = 39.4 J/K.mol
The change in temperature (ΔT) = 100 - 58 = 42 oC or 42 K
The no. of moles of H2O (n) = 4.31 mol
Now, ΔH = n*ΔCp*ΔT = 4.31 mol * 39.4 J/K.mol * 42 K = 7132.188 J or 7.132 kJ
Now, ΔS = ΔH/T = 7132.188 J/(58+273) K = 21.547 J/K
