What is the Difference Between Homogeneous and Heterogeneous Catalysis in Terms of Energy Levels?
In homogeneous catalysis, the catalyst and reactants are in the same phase, usually liquid. The energy levels are influenced by the interactions between the catalyst and reactants at a molecular level. In heterogeneous catalysis, the catalyst is in a different phase, typically solid, and the energy levels are affected by surface phenomena such as adsorption and desorption.
