Detailed explanation-2: -Catalysts play a critical role in modern industry. Today, catalysts are involved in the production of over 80 percent of all manufactured products. Moreover, approximately 90 percent of all industrial chemicals produced in the world use catalysts within the manufacturing process.
Detailed explanation-3: -Introduction to Catalysis Catalysts make it easier for a chemical reaction to occur.
