Question

The vapor pressures of heptane (substance 1) and octane (substance 2) are as follows:

Temp(°C)	vapor pressure heptane(mmHg)	vapor pressure octane (mmHg)
98.5	760	342
100	795	354
110	1047	482
120	1367	646
126	1560	760

Assuming the above liquid mixture obeys Raoult's law:

Sketch the diagram of the boiling point for a total vapor pressure of 760 mm Hg.
Determine the bubble point (bubble temp) if x 1 = 0.3 at 760 mm Hg.
Determine the dew point if y1 = 0.3 at 760 mm Hg
Make a P-xy equilibrium diagram at 110° C
Graphically calculate the bubble pressure if x1 = 0.6 at 110° C
Graphically calculate the dew pressure if y1 = 0.6 at 110 o C
