Question

how does catalyst work to speed up a chemical reaction?

Answer 1

a catalyst provide alternative route for the reaction with lower activation energy

Answer 2

heyy buddy❤✌❤

Catalysts speed up chemical reactions but remain chemically unchanged themselves at the end of the reaction.Catalysts work by lowering the activation energy of a reaction so that a higher proportion of particles have sufficient energy to react.
