An analysis is made of diffusion and chemical reaction in an isothermal multicomponent fluid. Transient gas‐phase reaction in a one‐dimensional nonflow system and steady state gas‐phase or surface reaction in a tubular reactor are considered. The equations are linearized around some state away from equilibrium. Multicomponent and binary diffusivity expressions are used and a series of reactions of varying complexity is considered. The possibility of oscillations increases as the complexity of the reactions is increased. These oscillations occur with time in the nonflow system and with space‐time in the tubular reactor, and it appears that any reacting mixture which oscillates in one of these two systems will also oscillate in the other.
