This graph shows how the vapor pressure of three liquids varies with temperature: 900 - 800 700- 600 500- 400 - 300 toluene ethylbenzene orthoxylene 200- 100- 100 110 120 130 140 temperature, °C Use the graph to answer the following questions: Which liquid is the most volatile? most volatile: choose one Which is the least volatile? least volatile: choose one toluene: What is the normal boiling point of each liquid? Note: your answer must be within 1°C of the exact answer to be graded correct. ethylbenzene: orthoxylene: Suppose a beaker of ethylbenzene is put inside a sealed tank containing ethylbenzene gas at 126. degree C and 566. torr. After ten minutes, will there be more liquid in the beaker, less liquid, or the same amount? more less the same vapor pressure, torr
