Problem: Consider the following vapor pressure versus temperature plot for three different substances: A, B, and C.If the three substances are CH 4, SiH4, and NH3, match each curve to the correct substance.

🤓 Based on our data, we think this question is relevant for Professor Davis' class at UCF.

FREE Expert Solution

Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed state (solid or liquid). Vapor pressure increases with temperature.


We will solve this problem through these steps:

  • Use the temperature-vapor pressure curve to have an idea of boiling points of A, B and C.
  • Compare the boiling points with the boiling points as predicted through the molecular structure.
