The effects on the propagation of sound of dissociation and recombination in a diatomic gas are discussed on the basis of kinetic theory for such a gas. A perturbation theory is used in which the perturbation incorporates the collision operator for reactions and the convective term in the Boltzmann equation. Consequently the sound frequency need not be small relative to the reaction rate, so the results describe the transition between slow and fast reaction regimes.
