Detailed explanation-1: -Catalysts break down paper pulp to produce the smooth paper in your magazine. They clean your contact lenses every night. They turn milk into yogurt and petroleum into plastic milk jugs, CDs and bicycle helmets.

Detailed explanation-2: -Catalysts make this process more efficient by lowering the activation energy, which is the energy barrier that must be surmounted for a chemical reaction to occur. As a result, catalysts make it easier for atoms to break and form chemical bonds to produce new combinations and new substances.

Detailed explanation-3: -The only effect of the catalyst is to lower the activation energy of the reaction. The catalyst does not affect the energy of the reactants or products (and thus does not affect E).

Detailed explanation-4: -Using a catalyst can save a lot of energy. Beyond that, it can also reduce waste since catalysts allow chemists to control the chemical reaction, reducing the creation of undesired by-products. Another added bonus is that the catalyst remains unchanged in most cases and is thus reusable.

Detailed explanation-5: -Catalysis (/kəˈtæləsɪs/) is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (/ˈkætəlɪst/). Catalysts are not consumed in the reaction and remain unchanged after it.
