Which of the following processes must exist in equilibrium with the condensation process when a measurement of vapor pressure is made?
A) evaporation
B) fusion
C) sublimation
D) boiling
E) none of these

Question

Quizplus · Accepted Answer

When measuring vapor pressure, the system must be in equilibrium between the rate of condensation and the rate of evaporation. The other processes listed (fusion, sublimation, and boiling) do not involve the same balance of vaporization and condensation, and therefore are not in equilibrium with the condensation process during vapor pressure measurement.
