Question

The process is taking place at constant temperature and pressure. then which of the following is true?

1)ΔH= ΔE
2)ΔH=TΔS
3)ΔH=0
4)ΔS=0

Answer 1

Answer: ΔH=TΔS

Both ΔH and TΔS are temperature dependent, where ΔH = TΔS. Because ΔG = ΔH − TΔS, at this temperature ΔG = 0, indicating that the liquid and vapor phases are in equilibrium.
