Questions 15-18 are related to material covered on exam 1 Chloroform has a normal boiling point of 61°C and a АHvap of 29.6 kJ/mol. Determine the vapor pressure (in atm) of chloroform u 29"C. Give you answer to 2 decimal places.
s. Consider propane, which has a normal boiling point of -42.0°C and a heat of vaporization of 19 kJ/mol. What is the vapor pressure at 25.0°C? 6. Atmospheric pressure on the surface of Mars averages 600 Pa (6 mbar) Use the phase diagram for water below to determine the boiling and melting points for water on the surface of Mars, assuming an atmospheric pressure of 800 Pa. Note that this chart uses a logarithmic scale, so the axes major unit...
