What Are Catalysts?

The video tutorial explains the concept of catalysts, which are substances that speed up chemical reactions without being consumed. Catalysts work by providing an alternative reaction pathway with lower activation energy, resulting in faster reactions. The tutorial highlights the use of catalysts in everyday life, particularly in manufacturing processes like the Haber process for ammonia production and the contact process for sulfuric acid production. Catalysts are also used in catalytic converters in vehicles to reduce toxic emissions. The video concludes with a recap of the key points discussed.
