1. The reported¹ Margules parameter for a binary mixture of methanol and benzene at 60 °C is A=0.56. At this temperature: Pat = 84 kPa Pat = 52 kPa where subscripts (1) and (2) are for methanol and benzene respectively. Use this information to find the equilibrium pressure (kPa) of a liquid-vapor mixture at 60 °C where the compo- sition of the liquid phase is z₁ = 0.25.

1.
The reported¹ Margules parameter for a binary mixture of methanol and benzene at 60 °C is
A=0.56. At this temperature:
Pat = 84 kPa
Pat = 52 kPa
where subscripts (1) and (2) are for methanol and benzene respectively.
Use this information to find the equilibrium pressure (kPa) of a liquid-vapor mixture at 60 °C where the compo-
sition of the liquid phase is r₁ = 0.25.
