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.
