This HW assignment is due Wednesday, ±ebruary 6, by 4:00PM. . 001 10.0 points The vapor pressure oF a liquid at 25 C is 200 torr. IF the pressure over the liquid is lowered to 190 torr at 25 C, the liquid will 1. Freeze. 2. evaporate. 3. boil. 002 10.0 points Consider two closed containers. Container X is a 2 L container that contains 0.5 L oF acetone. Container Y is a 3 L container that contains 1.8 L oF acetone. Both containers and contents are at 28 C. Which oF the Following is true? 1. The vapor pressures in both containers are equal. 2. The vapor pressure in container X is greater. 3. You would need inFormation about the shape oF the containers to be able to answer this question. 4. The vapor pressure in container Y is greater. 003 10.0 points Use the Clausius-Clapeyron equation to cal- culate the temperature at which pure water would boil at a pressure oF 416 torr. The heat oF vaporization oF water is 43080 J / mol at 100 C. Answer in units oF C. 004 10.0 points The phase diagram For a pure compound is given below.
