Answer to Question #71164 in General Chemistry for Paul

Question

at 50 degrees Celsius the vapor pressure of:

1.ethanol - 0.30 atm

2.acetic acid - 0.08 atm

3.water - 0.12

4.acetone - 0.84

a. arrange in order of increasing rates of evaporation
b. arrange in order of increasing boiling points
c. arrange in order of increasing IMF

Answer 1

a. In order of increasing rates of evaporation: acetic acid<water<ethanol<acetone (higher values of vapor pressure correspond to higher rates of evaporation);
b. In order of increasing boiling points: acetone<ethanol<water<acetic acid (higher values of vapor pressure correspond to lower values of boiling point);
c. In order of increasing IMF: acetone<ethanol<water<acetic acid.
