Question

Name a catalyst which increases the rate of chemical reaction

Answer 1

Answer:

Catalysis is the process of increasing or decreasing the rate of a chemical reaction by adding a substance known as a catalyst.

Two types of Catalyst

1. Positive Catalyst
2. Negative Catalyst

Explanation:

• Palladium catalysts : For cars that use unleaded gasoline, conduits with palladium or platinum in small particles adhere to the exhaust of cars, can catalyze the process of attenuation of carbon monoxide and other toxic gases of combustion, allowing to reduce them to less dangerous substances in record time.
• Derivatives of fluorine : Accelerate the decomposition of ozone in oxygen, a reaction that is usually slow. There is the problem of aerosols and refrigerants that release CFCs into the atmosphere: they catalyze in this sense the ozone layer.
• Magnesium dioxide (MnO 2 ) : A frequent catalyst in the decomposition of Hydrogen Peroxide or hydrogen peroxide in water and oxygen.
• Nickel : Used in the hydrogenation of vegetable oils, to obtain margarine, since this metal accelerates the process of obtaining saturated lipids.
• Silver : Polycrystalline and nanoporous silver are effective accelerators of carbon dioxide reduction processes (CO 2 ) through electrocatalysis.
• Aluminum Chloride : Used in the petrochemical industry to expedite the obtaining of synthetic resins or lubricants, without altering the delicate nature of hydrocarbons in question, since it has acidic and basic properties at the same time (amphoteric substance).
• The iron : It is used as a catalyst in the Haber-Bosch process to obtain ammonia from hydrogen and nitrogen.
