Worksheet: The Clausius–Clapeyron Equation
In this worksheet, we will practice using the Clausius–Clapeyron equation to convert between changes in temperature and vapor pressure.
When the temperature of a liquid is increased, the vapor pressure increases from to . How does the ratio vary with the enthalpy of vaporization?
For a compound , what enthalpy change is associated with the shown process?
- AEnthalpy of fusion
- BEnthalpy of vaporization
- CEnthalpy of formation
- DLattice enthalpy
- EEnthalpy of sublimation
Which of the following statements is incorrect?
- ATwo phases at equilibrium must have the same pressure.
- BThe maximum number of phases that can coexist in a system composed of four components is equal to six.
- CIt is impossible for four phases of a single pure substance to coexist at equilibrium.
- DThe Clausius–Clapeyron equation can be used in the characterization of solid–liquid phase equilibria.
Which of the following provides a succinct statement of the Clausius inequality?
- A for all isothermal processes carried out reversibly or irreversibly at a constant temperature .
- B for all spontaneous processes occurring in any kind of system.
- C for a spontaneous process occurring in an isolated system.
- D for any reversible process carried out at a constant temperature .
