Question:
Select the incorrect statement.
Select the incorrect statement.
Show Hint
Always remember that chemical adsorption is stronger and more specific, while physical adsorption is temporary and depends on surface area.
Updated On: Apr 1, 2025
- Physical adsorption is reversible, while chemical is irreversible.
- High pressure favors physical adsorption while low pressure favors chemical adsorption.
- Physical adsorption is not specific, while chemical adsorption is highly specific.
- High activation energy is required in chemical adsorption.
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
This statement is incorrect.
In physical adsorption, the process is favored at lower pressures, while chemical adsorption tends to be favored at higher pressures.
Physical adsorption is primarily driven by van der Waals forces, which are more significant at lower pressures.
Chemical adsorption involves stronger covalent bonding and is more pronounced at higher pressures.
