Vapor Pressure: Interpretation of Table H Using the vapor pressure curves in Regents Table H, answer the following questions:
1. What is the vapor pressure of ethanol at 50 °C.
2. How do the vapor pressure of the other substances compare to the vapor pressure
of
ethanol at 50 °C?
3. At what temperature does propanone have a vapor pressure of 180 kPa?
4. Which substance has a vapor pressure of 110 kPa at 120 °C?.
5. In order for water to boil at 70 °C, what must the pressure be?
6. What is the boiling point of ethanoic acid at 60 kPa?
7. Which substance has the highest normal boiling point?
8. Which substance has the lowest normal boiling point?
9. Explain how you arrived at your answer for # 8?
Estimate the following (from Regents Table H).
10. The vapor pressure of ethanoic acid at 80°C
11. The vapor pressure of water at 40°C.
