Homogeneous and Heterogeneous Catalysts 🎯 Learning outcomes Candidates should be able to: Explain that catalysts can be homogeneous or heterogeneous Describe the mode of action of a heterogeneous catalyst, including adsorption of reactants, bond weakening and desorption of products, for example: (a) iron in the Haber process (b) palladium, platinum and rhodium in the catalytic…
🎯 Learning outcomes After completing this lesson, you should be able to: explain and use the terms catalyst and catalysis explain that, in the presence of a catalyst, a reaction has a different mechanism — one of lower activation energy explain this catalytic effect in terms of the Boltzmann distribution construct and interpret a reaction…
