**At the triple point, all the three phases exist in thermodynamic equilibrium.**

$\mathbf{ln}\left({P}_{s}\right)\mathbf{=}\mathbf{ln}\left({P}_{t}\right)$

The vapor pressures (in torr) of solid and liquid uranium hexafluoride are given by

In (P_{s}) = 24.513 -

In (P_{1}) = 17.357 -

Where T is the absolute temperature. Calculate the temperature and pressure at the triple point of uranium hexafluoride.
