Driving Forces
This refers to the process by which molecules move from an area of high to low concentration.
What is diffusion?
This process uses difference in boiling point to separate mixtures.
What is distillation?
On a Txy or Pxy diagram, this curve represents the temperature or pressure at which a liquid will begin to condense.
What is the dew point curve?
This graphical method is used to determine the number of ideal stages in distillation.
What is the McCabe-Thiele method?
What is the Bible?
What must be equal in all phases in equilibrium?
What is chemical potential OR fugacity?
This process removes a volatile substance from a liquid mixture via contact with another gas.
What is stripping?
When this point is present on a Txy, Pxy, or xy diagram, it indicates that the two components are difficult to separate.
What is an azeotrope?
Under this condition, a column would require infinite stages to achieve a given separation.
What is minimum reflux?
What is his bath?
In VLE, this law relates partial pressure to liquid composition for ideal mixtures.
What is Raoult's Law?
This separation process takes advantage of the fact that mixture components interact differently with a stationary phase and travel at difference speeds through a medium.
What is chromatography?
The ease with which two components can be separated is represented by this characteristic of their Txy or Pxy diagram.
What is the distance between the bubble point and dew point curve?
This undesirable phenomenon occurs when vapor velocity is so high that liquid becomes entrained in vapor.
What is flooding?
This was the original title of Catch-22.
What is Catch-18?
What thermodynamic quantity is maximized at equilibrium instead of being minimized?
What is entropy?
This separation method uses a solvent to selectively remove one or more components from a liquid mixture based on differences in solubility.
What is liquid-liquid extraction?
In a two-liquid-phase diagram, this point marks where the two phases become identical and tie lines shrink to zero length.
What is the plait point?
These columns are used when the mixture to be separated is likely to foam and has the advantage of requiring a smaller diameter than a tray column.
What is a packed column?
Agathe Christie had this job before she became a mystery writer, which somewhat explains her extensive knowledge of poisons and chemicals.
What is an apothecary's assistant (dispenser)?
Two components will separate into two liquid phases instead of existing as a single phase because the system can achieve this condition.
What is lower/minimal Gibbs free energy?
This process separates a mixture based on differences in their ability to bind to a solid surface.
What is adsorption?
This diagram can be used to determine the compositions of the raffinate and extract when a three-component system separates into two liquid phases.
What is a ternary phase diagram?
This stage-by-stage calculation method forms the basis for the graphical McCabe-Thiele method.
What is the Lewis method?
Rick Riordan originally created Percy Jackson as a standalone story for this group of people.
What is his middle school mythology class?
