1. Transient State Analysis: It allows for the study of transient intermediates that are often undetectable in steady-state experiments. 2. Kinetic Information: Detailed kinetic data can be obtained, helping to elucidate reaction mechanisms. 3. Catalyst Testing: Provides a method for testing catalyst stability and activity under dynamic conditions. 4. Minimized Deactivation: Reduces the risk of catalyst deactivation by avoiding continuous exposure to reactants.
