Chapter 17, Problem 50E

Interpretation Introduction

Interpretation: The composition of the ideal solution of benzene and toluene needs to be determined.

Concept introduction: From Raoult’s law it can be given as, ${\chi }_A$

  $P=P^0{}_A{\chi }_A+P^0{}_B{\chi }_B$

Here,

  $P$ = total vapor pressure of the solution

  ${\chi }_A$ = mole fraction of component A

  ${\chi }_B$ = mole fraction of component A

  $P^0{}_A$ = vapor pressure of component A

  $P^0{}_B$ =vapor pressure of component B
