How do different factors affect reaction rate

WebHow do catalysts affect the rate of a reaction? Catalysts 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. http://pressbooks-dev.oer.hawaii.edu/chemistry/chapter/factors-affecting-reaction-rates/
