What is the difference between a catalyst and a promoter?
Asked by mkp400 | 21st Oct, 2017, 08:23: PM
Expert Answer:
A catalyst is a substance which decreases the activation energy of a chemical reaction without itself being changed at the end of the chemical reaction.
A promoter is an accelerator of catalysis, but not a catalyst by itself.
Promoter is a material that enhances the action of a catalyst without actually having any catalytic value itself.
