Desorption kinetics can be modeled using various approaches, including:
1. First-Order Kinetics: This model assumes that the rate of desorption is directly proportional to the coverage of the adsorbate on the surface. 2. Second-Order Kinetics: In this model, the desorption rate is proportional to the square of the adsorbate coverage, often applicable when desorption involves the recombination of two adsorbed species. 3. Langmuir-Hinshelwood Mechanism: It combines adsorption, surface reaction, and desorption steps, providing a more comprehensive model for heterogeneous catalysis. 4. Eyring Equation: This transition state theory-based model can be used to describe the temperature dependence of desorption kinetics.
