  • What is an example of a catalytic reaction?

  • Other examples of Catalytic Reactions. The halogenation of benzene. Benzene reacts with chlorine or bromine in the presence of a catalyst. The catalyst used can either be aluminum chloride or iron. Strictly talking about iron is not a catalyst, because it gets permanently changed during the reaction.

  • What is a catalyst in chemistry?

  • A catalyst in chemistry can be simply defined as a substance that enhances the speed of the chemical reaction itself remaining unaltered in mass, activity, and chemical composition.

  • Does a catalyst affect the energy of the reactants or products?

  • There is no effect on the energy of the reactants or the products. How Catalysts Work. Catalysts permit an alternate mechanism for the reactants to become products, with a lower activation energy and different transition state. A catalyst may allow a reaction to proceed at a lower temperature or increase the reaction rate or selectivity.

  • What are the types of catalysis?

  • Ans: A catalyst is a chemical substance that accelerates a chemical reaction. The phenomenon which involves the action of a catalyst is called catalysis. Based on this concept catalysis are divided into two main types: (i) Homogeneous catalysis and (ii) Heterogeneous catalysis.
