In this Lecture, we apply the canonical ensemble to treat equilibria between reacting chemical species. For low-pressure gases, chemical equilibria are determined primarily by single molecule properties, so equilibrium constants can be computed using little more than spectroscopic data. Such computations have potential practical use. Under some physical conditions, notably extreme high temperature, it may be easier to calculate equilibrium constants than to measure them.
