Unusual chemical thermodynamics

Thermodynamics is truly a universal science, and its applications to phenom ena outside the chemical laboratory or processing plant are many. Two are d iscussed here; the prediction of the high-temperature chemical equilibria a nd transport properties needed for the design of interplanetary probes, and the distribution of long-lived chemicals throughout the environment. Also, the possibilities of combining ab initio quantum calculations with activit y coefficient models and equations of state to make predictions of vapor-li quid equilibria over large ranges of temperature and pressure is illustrate d.
