Question

What is acid base catalysis ? Explain the theories of acid -base catalysis with suitable example?​

Answer 1

Answer:

A catalyst is a substance that alters the rate of chemical reaction without itself being permanently chemically changed. Never state things like "it doesn't react, just speeds it up". It must take part in the reaction and it must change chemically, albeit on a temporary basis. This may involve chemical intermediates or even superficially on the surface of a solid catalyst.

A catalyst lowers the activation energy (Ea) by providing a different 'pathway' or mechanism that makes the bond breaking processes (or other electronic changes in the reactants) occur more readily.

Explanation:

In acid catalysis and base catalysis, a chemical reaction is catalyzed by an acid or a base. By Brønsted–Lowry acid–base theory, the acid is the proton donor and the base is the proton acceptor. Typical reactions catalyzed by proton transfer are esterfications and aldol reactions.

Theories of catalysis explain the influence of the catalysts upon the rate of a reaction by describing the detailed mechanism by which the catalyst is involved in the steps of the chemical reaction.
