Описание: This video looks at the action of catalysts. As an example of heterolytic catalysis the decomposition of hydrogen peroxide in the presence of manganese (IV) oxide is considered. As an example of homolytic catalysis the production of ethanol by the hydration of ethene in the presence of phosphoric acid catalyst is considered. The animations attempt to show you the bond-breaking and bond-forming that goes on - illustrating how catalysts produce more reactive intermediates that provide an alternative reaction pathway with a lower activation energy.
