Abstract:

The master equation, as described in part I of this series, is solved numerically for the dissociation of H2 diluted in He, and also for the reverse reaction, the recombination of H atoms, using an assumed set of transition probabilities. In both processes, it is found that the total entropy is a completely monotonic function of the time. Once the transient period is over, the phenomenological rate constants for both dissociation and recombination remain virtually independent of time and conform accurately to the rate-quotient law there are, however, some conditions attached to this statement if integrated rate constants are used.
