EXERCISE

Benzene $(1)$ Toluene$(2)$ are mixed with each other in

a pressure vessel. The cylindrical vessel with a diameter

of $50cm$ and a height of $30cm$ placed in a heater

So the temperature in the vessel is kept constant at $50C$

the benzene and Toluene turn to an ideal mixture.

$-$ Calculate the saturation pressure of the liquide

mixture Ps$($fl$),$ when the pressure vessel is

completely filled with a mixture containing $20$

liters of Be

$-$How bar must the pressure be lowered to

reach the condensation pressure Ps$($gas$)($the

pressure at wich the mixture is completely in

the saturated vaporization phase?

$-$ What mole fraction of Toluene must be set

in the mixture contain?

$-$ Plot the saturation pressure of the liquid phase

and the condensation pressure a function of the

mole fraction of Tolvene $(x_2=x_{\text{T}\text{o}\text{l}\text{m}\text{o}\text{l}})$ in

The attached diagram use the attached value

Table for this purpose Use the folowing substance values of the pure

substance for $=50C$
