Which of the following statements is incorrect w.r.t. inorganic catalyst?

Options

A. They do not occur in living cells
B. They are not specific for any reaction
C. They get damaged at high temperature
D. They work efficiently at high pressure

Answer

To determine which statement is incorrect with respect to inorganic catalysts, let's analyze each statement one by one:

1. **Statement 1**: "They do not occur in living cells."
- Inorganic catalysts, such as platinum, palladium, and nickel, are typically used in laboratory settings and industrial processes rather than in biological systems. Therefore, this statement is **true**.

2. **Statement 2**: "They are not specific for any reaction."
- Inorganic catalysts can catalyze a variety of reactions and are not limited to a specific type of reaction. For example, platinum can be used in hydrogenation reactions. Hence, this statement is also **true**.

3. **Statement 3**: "They get damaged at high temperature."
- Inorganic catalysts generally have a high thermal stability and do not get damaged at high temperatures. This statement is **false**, making it the incorrect statement regarding inorganic catalysts.

4. **Statement 4**: "They work efficiently at high pressure."
- Inorganic catalysts often perform better under high-pressure conditions as this can increase the reaction rate and efficiency. Thus, this statement is **true**.

**Conclusion**: The incorrect statement regarding inorganic catalysts is that "they get damaged at high temperature."
