Question

what is catalyst explain in detail

Answer 1

a catalyst is something that speeds up the reaction without being used up. this is done by using an alternative route with lower activation energy.

Answer 2

A catalyst is a substance that speeds up a chemical reaction, but is not consumed by the reaction; hence acatalyst can be recovered chemically unchanged at the end of the reaction it has been used to speed up, or catalyze. ... A catalyst works by providing a different route, with lower Ea, for the reaction.
