Pure chlorobenzene is contained in a flask attached to an open-end mercury manometer. When the flask contents are at 58.3°C, the height of the mercury in the arm of the manometer connected to the flask is 747 mm, and that in the arm open to the atmosphere is 52 mm. At 110°C, the mercury level is 577 mm in the arm connected to the flask, and 222 mm in the other arm. Atmospheric pressure is 755 mmHg. (a) Using the data given, find deltaHv and B in the Clausius-Clapeyron equation. (b) Air saturated with chlorobenzene at 130°C and 101.3kPa (absolute) is cooled to 58.3°C at constant pressure. Estimate the percentage of the chlorobenzene originally in the vapor that condenses. (Hint: draw a flowchart with separate vapor and liquid streams)
nitrogen slowly expands from an initial volume of 0.025 m3 to 0.05 m3 at a constant pressure of 400 kpa. then heat is
