normal boiling point

Post by anto007 »

Hi everyone, I have this exercise: 'Which of the following values represents the normal boiling point of carbon tetrachloride? Use the thermodynamic data given.
CCl4.JPG
CCl4.JPG (21.47 KiB) Viewed 1847 times
a)-272°C
b) 25°C
c) 67°C
d) 69°C
e) 109°C. "
I thought of applying the following formula:
\(ΔG°= 0\); \(ΔG°=ΔH°-TΔS°\)
but my result deviates a lot from the experimental data.
Will you help me understand how to solve it?
Thanks a lot

Yes, I know, but how can I calculate it with the thermodynamic data provided in the text?
Whether or not the correct result is among those proposed.
