- Step Change in Concentration: This involves abruptly changing the concentration of a reactant or product. For example, switching from an inert gas to a reactant gas allows the study of adsorption and reaction kinetics. - Pulse Experiments: A small amount of reactant is introduced as a pulse, and the system's response is observed. This is useful for studying fast reactions and the behavior of intermediates. - Temperature Jumps: Rapid changes in temperature can provide information on activation energies and the temperature dependence of reaction rates. - Flow Rate Changes: Altering the flow rate can help understand transport limitations and the interplay between diffusion and reaction kinetics.
