What are catalysts used for?

Answer 1

Catalysts are a complex compound that fastens the rate of reaction when added in a chemical reaction. In a normal chemical reaction, it takes say, 1 hour but while using catalysts, the rate of reaction increases so the resulting time would be less. But making no physical or chemical changes to the reaction. The way a catalyst works is simple. All it does is, absorb the reactant particles onto its surface and absorb their bond energy, making their bonds weaker. In a chemical reaction, Reactant particles need to collide with sufficient kinetic energy to overcome the activation energy for the reaction to proceed. A catalyst lowers the activation energy, so than particles with lower energy can also initiate the reaction.

Answer 2

Catalysts are used to speed up chemical reactions by lowering the activation energy needed for the reaction to occur. They remain unchanged at the end of the reaction and can be reused multiple times. Catalysts are widely used in industries such as pharmaceuticals, petrochemicals, and environmental applications.

Answer 3

Catalyst are enzymes used for speeding up chemical reaction in body cells.
