Adsorption of a gas on a surface follows the Freundlich adsorption isotherm. The plot of $\log \frac{x}{m}$ versus $\log P$ gives a straight line with a slope equal to $0.5$. Then,(where $\frac{x}{m}$ is the mass of the gas adsorbed per gram of adsorbent):
- AAdsorption is independent of pressure.
- BAdsorption is proportional to the pressure.
- CAdsorption is proportional to the square root of pressure.
- DAdsorption is proportional to the square of pressure.
