Thermodynamic properties and phase equilibria behavior for the hydrate
s and coexisting pairs of hydrates of common acids which exist in the
stratosphere are assembled from new laboratory measurements and standa
rd literature data. The analysis focuses upon solid-vapor and solid-so
lid-vapor equilibria at temperatures around 200 K and includes new cal
orimetric and vapor pressure data. Calculated partial pressures versus
1/T slopes for the hydrates and coexisting hydrates agree well with e
xperimental data where available.
