a) Calculate the difference in molar entropy between (i) -5 C water and -5 C ice (ii) 95 C water and 95 C vapour (p = 1 atm). b) Calculate the change in total entropyls for the change at -5 C and g 1 for the change at 95 C. Are these processes spontaneous? Given data: ACS kJ/mol. g Acam = 37.3 J/Kmol, acom = 41.9 J/Kmol, AHm,fus AC = = 6.01 kJ/mol and AHm,evap = = 40.7 p Note: 1 AC and Achoma refer to the differences in molar heat capacity on melting and vaporization, AC respectively. pim p AHm,fus refers to the molar enthalpy of fusion (i.e., melting) of ice. AHm,evap refers to molar enthalpy of vaporization of water
