Explanation In the given solution, 1 , 2 − dimethylbenzene is assumed as component A and 1 , 3 − dimethylbenzene is assumed as component B. The expression to calculate the composition of liquid mixture is, p = ( x A p A * + x B p B * ) (1) Where, x A is the mole fraction of component A. p A * is the vapour pressure of pure component A. x B is the mole fraction of component B. p B * is the vapour pressure of pure component B. p is the total vapour pressure. The value of p A * is 20 kPa . The value of p B * is 18 kPa . The value of p is 19 kPa . Substitute the values of p A * , p B * and p in the equation (1). 19 kPa = ( x A × 20 kPa + x B × 18 kPa ) (2) The mole fraction of component B ( x B ) is, x B = ( 1 − x A ) (3) Substitute the equation (3) in equation (2). 19 kPa = ( x A × 20 kPa + ( 1 − x A ) × 18 kPa ) x A ( 20 kPa − 18 kPa ) = 19 kPa − 18 kPa x A = 0

Question

Chapter 5, Problem 5B.10BE

Interpretation Introduction

Interpretation: The composition of mixture at 90° C at a given pressure has to be calculated. The composition of the vapour produced has to be calculated.

Concept introduction: According to the Raoult’s law the vapour pressure of the solution is equal to the product of vapour pressure of the solvent and its mole fraction in the solution.
