Question

explain how to get the center temperatures because thats where I am having most issues

This graph shows how the vapor pressure of three liquids varies with temperature: 000- 700 600 olo s00 400 300 benzene isopropyl acetate tetrahydrofuran 700 100 60 0 80 temperature, C Use the graph to answer the following questions: tetrahydrofuran most volatile: Which liquid is the most volatile? Which is the least volatile? choose one least volatile: benzene: 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 isopropyl acetate: tetrahydrofuran: Suppose a beaker of isopropyl acetate is put inside a sealed tank containing isopropyl acetate gas at 80 degree C and 738. torr. After ten minutes, will there be more liquid in the beaker, less liquid, or the same more less the same amount? ? X aunssaud odeA

Answer 1

Boiling point is the temperature at which vapour pressure of liquid becomes equal to the atmospheric pressure. Atmospheric pressure = 760 torr.

So to find out the boiling point just check the temperatures of the curves which corresponds to vapour pressure of 760 torr.

For tetrahydrofuran it comes out to be 65 deg, for benzene 80 deg and for isopropyl acetate 89 deg.
