Catalysts and Homogeneous and Heterogeneous Catalysis (A-Level IB Chemistry)

Outlining the role of catalysts in the rates of reactions, linked to activation energy and Maxwell-Boltzmann distribution curves. Homogeneous and Heterogeneous catalysts and catalysis is covered, with examples of each given including the reaction of iodide ions with thiosulfate ions (Fe2+ catalyst) and the contact process between sulfur dioxide and oxygen (V2O5 catalyst).
