How does catalyst affect a chemical reaction
WebThe role of a catalyst in chemical reactions is best explained by intermediate-complex theory. According to intermediate-complex theory, it brings down the activation energy for a reaction or provides a different pathway for the reaction where activation energy is lower. It makes temporary bonds with the reactant molecules to form an ... WebA catalyst is a substance that speeds up the rate of a chemical reaction.
