Phase Equilibria Flashcards
The equilibrium between two phases in a given situation is restricted by __________.
Phase Rule
Useful in predicting the number of intensive variables that may be varied independently in any system.
Phase Rule
Number of phases at equilibrium
P
Number of total components in the two phases when no chemical reactions are occurring.
C
The number of variants or degrees of freedom of the system.
F
A graphical representation of the physical states of a substance under different conditions of temperature.
Phase Diagram
It states that the partial vapor pressure of each component of an ideal mixture of liquids is equal to the vapor pressure of the pure component multiplied by its mole fraction in the mixture.
Raoult’s Law
An approximation that is generally valid when X is close to 1- that is when the liquid is almost pure A.
Raoult’s Law
The temperature at which the saturated vapor starts to condense.
Dew Point
The temperature at which the liquid starts to boil
Bubble Point
It shows the boiling points of a binary mixture as a function of the vapor/liquid equilibrium of the mixture at constant pressure.
Boiling Point Diagram
A mixture of two or more liquids with an equilibrium vapor of the same composition as the liquid.
Azeotrope
The resulting vapor has the same ratio of constituents as the original mixture.
Azeotropic Mixture
It states that the amount of dissolved gas in a liquid is directly proportional to its partial pressure above the liquid.
Henry’s Law
