Incorrect Statement about Inorganic Catalysts

Inorganic catalysts are substances that accelerate the rate of chemical reactions without undergoing any permanent change themselves. They are widely used in various industries, including chemical, pharmaceutical, and petrochemical, to increase the efficiency of chemical reactions. However, one of the following statements about inorganic catalysts is incorrect:

"They get damaged at high temperature."

Explanation:

Inorganic catalysts are known for their robustness and stability, which makes them suitable for use in extreme conditions such as high temperatures and pressures. They can withstand high temperatures without getting damaged or degraded, which is one of their advantages over organic catalysts. In fact, some inorganic catalysts work more efficiently at elevated temperatures, as it increases the rate of reaction. Therefore, the statement that inorganic catalysts get damaged at high temperature is incorrect.

Other Statements about Inorganic Catalysts:

1. They do not occur in living cells

Inorganic catalysts do occur in living cells, such as metalloenzymes, which are proteins that contain metal ions that act as catalysts. Some examples of metalloenzymes are carbonic anhydrase, which catalyzes the conversion of carbon dioxide to bicarbonate, and cytochrome oxidase, which catalyzes the reduction of oxygen to water during cellular respiration.

2. They are not specific for any reaction

Inorganic catalysts can be specific for certain reactions, depending on their chemical properties and structure. For example, platinum is a catalyst commonly used in the automotive industry to catalyze the conversion of harmful gases such as carbon monoxide and nitrogen oxides into less harmful substances. Other catalysts such as zeolites are specific for certain types of reactions such as cracking of hydrocarbons.

3. They work efficiently at high pressure

Inorganic catalysts can work efficiently at high pressure, as it increases the rate of reaction by providing more energy to the reactants. This is particularly useful in the petrochemical industry, where high-pressure reactions are used to produce various chemicals. However, some catalysts may have limitations in terms of pressure range, and their efficiency may decrease beyond a certain pressure.
