Показать описание
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).

For AQA, OCR, Edexcel and CIE

I'm so glad you explained that the activation energy is overcome by sufficient kinetic energy. Many explanations just indicate that particles need to have sufficient energy to overcome the activation energy.
