This dissertation is concerned with the kinetics of the nonequilibrium dissociation and ionization of gases that are significant in the high temperature gas dynamics. There are two parts in the dissertation. In the first part, the kinetics of dissociating gas, a theoretical calculation is made of the nonequilibrium dissociation of the diatomic molecule behind a strong shock wave front.
