How does catalysts affect rate of reaction

WebFortunately, it’s possible to lower the activation energy of a reaction, and to thereby increase reaction rate. The process of speeding up a reaction by reducing its activation energy is known as catalysis, and the factor that's added to lower the activation energy is called a catalyst. Biological catalysts are known as enzymes, and we’ll ... 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 ...
