Chapter 15, Problem 48E

Use the following vapor pressure data to answer the questions:

	Liquid	Vapor pressure (torr)	Temperature $\left(\text{°C}\right)$
$\text{A}$	${\text{CH}}_3{\text{COOCH}}_{\text{3}}$	$400$	$40.0$
$\text{B}$	${\text{C}}_{\text{7}}{\text{H}}_{\text{16}}$	$400$	$78.0$

In which liquid are the intermolecular attractive forces the strongest? Explain. Will the vapor pressure of ${\text{CH}}_3{\text{COOCH}}_{\text{3}}$ at $\text{78}\text{°C}$ be higher or lower than $\text{400}\text{torr}$? Explain.
