Question

why catalyst are very specific in nature?​

Answer 1

A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process.

Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.

Answer 2

Catalytic surface is generally inactive in nature. When a reactant is adsorbed on the catalyst surface, it makes the catalyst active. This incites the further process of reaction. Catalysts are highly specific in nature, that is, what may be a catalyst for one can be an inhibitor for another. Some catalysts with same set of reactants give different products in comparison to other catalysts.
