Asolution contains two isomers, n-propyl alcohol and isopropyl alcohol, at 25°c. the total vapor pressure is 38.6 torr. what are the mole fractions of each alcohol in the liquid and in the vapor phase? the vapor pressures are 21.0 torr for n-propyl alcohol and 45.2 torr for isopropyl alcohol.

Mole fraction of alcohols in liquid phase .

Mole fraction of alcohols in vapor phase .

Explanation:

The total vapor pressure of the solution = p =38.6 Torr

Partial vapor pressure of the  n-propyl alcohol =

Partial vapor pressure of the isopropyl alcohol =

 (Raoult's Law)

is mole fraction in liquid phase.

Mole fraction of components in vapor phase

(Dalton's law of partial pressure)

Mole fraction of alcohols in vapor phase

the energy to form plasma comes from heat or electricity in the atmosphere!
