Interpretation Introduction

(a)

Interpretation:

Derive an expression of a and b.

Concept introduction:

Raoult’s law equation is given as,

yP=xP*

Where, P = the pressure of the system, y = mole fraction in vapor, x = mole fraction in liquid and P* = vapor pressure

Interpretation Introduction

(b)

Interpretation:

Calculate the mole fraction of pentane in the vapor phase for the given case and estimate a and b.

Concept introduction:

Raoult’s law equation is given as,

yP=xP*
