Discovering Reaction Molecularity

The video tutorial explains the difference between elementary and complex reactions. It introduces the concept of reaction mechanisms and molecularity, defining them as the number of reactant species involved in a collision. The tutorial categorizes elementary reactions into unimolecular, bimolecular, and termolecular, providing examples such as the decomposition of phosphorus pentachloride and hydrogen iodide. It also illustrates a hypothetical bimolecular reaction and discusses the formation of carbon dioxide as a termolecular reaction. Finally, it highlights the differences between the order of reaction and molecularity.
