Question:
Freundlich adsorption isotherm: log(mx) vs log(p) increases then flattens (points C-D). Experimental condition represented by C-D?
Freundlich adsorption isotherm: log(mx) vs log(p) increases then flattens (points C-D). Experimental condition represented by C-D?
Show Hint
In adsorption isotherms, flattening occurs at high pressure due to saturation of surface sites.
Updated On: Mar 6, 2026
- Saturation due to very low pressure
- Saturation due to high pressure
- Saturation due to variable temperature
- Saturation due to variable volume
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
At high pressure, adsorption sites are fully occupied → adsorption reaches maximum → flattening of Freundlich isotherm. Low pressure does not saturate adsorption.
