4 You are given the phase diagram shown and asked to determine several properties of the substance. First, find the normal melting point and boiling point. Pressure in atm 1.00- 0.75- 0.50- 0.25- 0 -50 solid -25 liquid -B- gas 0 25 Temperature, °C D 50 E This data does not extend to high enough pres- sure to determine the normal melting and boiling points of this substance. The normal melting point is ~-10 degrees Cel- sius, and the normal boiling point -50 degrees Celsius. This substance has a triple point so the normal melting and boiling points are the same.
An unknown liquid has a heat of vaporization of 9.40 kJ/mole. If the vapor pressure of this liquid at -193 degrees C is 111 torr, what is the normal boiling point of this liquid in degrees C? HINT: Normal boiling point occurs when the vapor pressure of the liquid is the same as atmospheric pressure (1 atm or 760 mm Hg).
An unknown liquid has a heat of vaporization of 5.06 kJ/mole. If the vapor pressure of this liquid at -194 degrees C is 101 torr, what is the normal boiling point of this liquid in degrees C? HINT: Normal boiling point occurs when the vapor pressure of the liquid is the same as atmospheric pressure (1 atm or 760 mm Hg). Your Answer:
An unknown liquid has a heat of vaporization of 39.70 kJ/mole. If the normal boiling point is 83, what is vapor pressure (in torr) of this liquid at room temperature of 25 degrees C? HINT: Normal boiling point occurs when the vapor pressure of the liquid is the same as atmospheric pressure (1 atm or 760 mm Hg).
