Question

What is the function of catalyst in a chemical reaction?

Answer 1

Answer:

A catalyst is a chemical substance which alters the rate of a reaction Without itself undergoing any permanent chemical change. In the chemical reactions, catalyst provides an alternate pathway or reaction mechanism by reducing the activation energy between reactants and products and hence.

Answer 2

Catalyst plays an important role in any chemical reaction. They are basically used for increasing the rate of chemical reaction.

The feature of Catalyst in the Chemical Reaction are :-

• It never initiates a chemical reaction. It just help to increase or decrease the rate of chemical reaction.
• It can be in state of matter which is solid, liquid or gas. However, it combines with the reactants in the intermediate steps and faciltates the chemical reaction.
• They can be used to break or make the chemical bonds in the reaction taking place.

Catalysts are mainly of two types:-

Homogenous Catalysts - It is in sync with the state of reactant. If the reactants are liquid in form, then the catalyst are alos in the same form.

Heterogenous Catalyst - It is defined as those catalyst which are not similar to that of reactants phase. It usually occur in Solid form and used for industrial purposes.
