Finding dew point P (isothermal compression example)You have a gas mixture of 15.0 mole % Benzene, 10.0 mole percent Toluene, and the rest being nitrogen gas, at a temperature of 80 °C. This is isothermally compressed until condensation occurs (dew). Find the pressure at which condensation begins (i.e. the dew point) and the composition of the initial condensate. Assume the system is modeled after Raoult’s law.Note: Dew point occurs when a vapor mixture forms its first drop of liquid. So dew point pressure is the pressure where a vapor mixture reaches the phase boundary and becomes a vapor-liquid mixture.

Finding dew point P (isothermal compression example)
You have a gas mixture of 15.0 mole % Benzene, 10.0 mole percent Toluene, and the rest being nitrogen gas, at a temperature of 80 °C. This is isothermally compressed until condensation occurs (dew). Find the pressure at which condensation begins (i.e. the dew point) and the composition of the initial condensate. Assume the system is modeled after Raoult’s law.
Note: Dew point occurs when a vapor mixture forms its first drop of liquid. So dew point pressure is the pressure where a vapor mixture reaches the phase boundary and becomes a vapor-liquid mixture.
