What are the Theoretical Models for Desorption Kinetics?
Desorption kinetics can be described using various theoretical models, such as:
1. Langmuir Desorption Model: Assumes that desorption is a first-order process and that the surface is homogeneously covered by the adsorbate. 2. Elovich Equation: Often used for systems with heterogeneous surfaces or when the desorption rate decreases exponentially with time. 3. Rate Equations: Derived from transition state theory, these equations take into account the activation energy and frequency factor for desorption.
