Chem, please help!!!!Calculate the equilibrium vapor pressure of naphthalene (C10H8) in the flask at 35°C.?

Question

A sample of solid naphthalene is introduced into an evacuated flask. Use the data below to calculate the equilibrium vapor pressure of naphthalene (C10H8) in the flask at 35°C.
===========ΔH°f (25°C)====ΔG°f (25°C)
C10H8(s)====78.5 kJ/mol=====201.6 kJ/mol

C10H8(g)====150.6 kJ/mol====224.1 kJ/mol



A) 890. mmHg
B) 0.21 mmHg
C) 696 mmHg
D) 0.086 mmHg
E) 833 mmHg

Answer 1

I am sorry, but naphthalene can not have two different ΔH°f and ΔG°f at 25°C.
