How Does a Catalyst Affect The Rate of Chemical Reactions?

WebSmaller particles have a larger surface area for their size than larger ones. This explains why powder normally reacts faster than lumps. Catalysts – A catalyst is a substance that changes the rate of a chemical reaction, but is chemically unchanged at the end of the reaction. An inhibitor does the opposite – it slows down chemical reactions. WebCatalysts speed up chemical reactions. Only very minute quantities of the catalyst are required to produce a dramatic change in the rate of the reaction. This is really because the reaction proceeds by a different pathway when the catalyst is present essentially lowering the activation energy required for the reaction to take place.
