Question

Name the different types of catalysts.

Answer 1

Hint: In the given question, we are required to name and give a brief description about the different types of catalysts. Catalysts are also used to break or build chemical bonds between the atoms which are present in the molecules of the reactants.

Complete answer:
Catalysts are defined as the chemical substances which alter the rate of reaction by changing the path of reaction. The basic principle of using a catalyst is to change the path of the reaction such that the activation energy of the reaction becomes lower or higher than in the original reaction. In general, a catalyst is used to speed up or speed down a particular reaction.
There are two types of catalysts: Positive catalysts and Negative catalysts
Positive catalysts are the catalysts that increase the rate of a chemical reaction by lowering the activation energy, thereby increasing the percentage yield of products.
Negative catalysts are the catalysts that decrease the rate of a chemical reaction by increasing the activation energy, thereby decreasing the percentage yield of products.

Note:
We must know about the activity of catalysts and their role in the reactions in order to answer such types of questions. Positive and Negative catalysts are the two types of chemical substances that either speed up or speed down the rate of a reaction. The negative catalysts are also known as poison.
