1. (32 points) Phase equilibrium: deriving an equation for the vapor-solid equilibrium (VSE) curve Under certain conditions, solid and vapor can be in equilibrium with each other. An example would be the naphthalene balls that are used to prevent insects from destroying clothes in storage. The derivation of the Clausius-Clapeyron equation, which relates the pressures and temperatures of points on the vapor-liquid equilibrium curve, is posted on Canvas in module Homework Supporting Materials. Using the same procedure, a similar equation for the pressures and temperatures of points in the vapor-solid equilibrium curve can be obtained. Derive this VSE equation. It should contain the heat of sublimation, hsg. State all principles, equations, and assumptions used in your derivation. 1.
