2. VLE : MODIFIED RAOULTS LAW APPROACH
A 60(1 ) : 40(2) liquid blend of unknown compound A (1) and B (2) is in equilibrium with its vapor at 291.20 F. At this temperature, an azeotrope is formed in which x1az = 0.294 and that the saturation pressures of the first and second component is equal to 0.742atm and 0.312atm respectively.
If the natural logarithm of activity coefficient of a given component is equal to the product of one parameter Margules coefficient, A multiplied by the square of the other component’s liquid mole fraction; solved for the
following :
a. The Margules coefficient, A
b. Equilibrium pressure P
c. Vapor composition of component 1
