a) For the boiling point of ethanol is 173.1 F. In an experiment the entropy change for the reaction CH3CH2OH(l) yields CH3CH2OH (g) the entropy change was determined to be 120.9 J/mol K. Please estimate the enthalpy if evaporation. ANSWER FOR PART A: -42.5kJ PART B (THE PART I NEED HELP WITH) For the reaction in part A determine the SIGNS of ΔH and the SIGNS and VALUE of ΔG at 100 F. (Note Δ H can be - or +) and ΔG can be (-,0,+)

THIS PROBLEM HAS TWO PARTS I CONFUSED ON PART 2 I HAVE ALREADY FIGURED OUT PART A BUT I HAVE INCLUDED IT BECAUSE PART B WOULDN'T MAKE SENSE WITHOUT IT.
a) For the boiling point of ethanol is 173.1 F. In an experiment the entropy change for the reaction CH3CH2OH(l) yields CH3CH2OH (g) the entropy change was determined to be 120.9 J/mol K. Please estimate the enthalpy if evaporation.
ANSWER FOR PART A: -42.5kJ
PART B (THE PART I NEED HELP WITH)
For the reaction in part A determine the SIGNS of ΔH and the SIGNS and VALUE of ΔG at 100 F. (Note Δ H can be - or +) and ΔG can be (-,0,+)
