The temperature dependence of the vapour pressure of solid sulfur dioxide can be approximately represented by the relation log(p/Torr) = 10.5916 − (1871.2 K)/T and that of liquid sulfur dioxide by log(p/Torr) = 8.3186 − (1425.7 K)/T. Estimate the temperature and pressure of the triple point of sulfur dioxide.
