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.

View SolutionFor Freundlich adsorption isotherm,a plot of $\log (x / m)$ ($y$-axis) and $\log p$ ($x$-axis) gives a straight line. The intercept and slope for the line is $0.4771$ and $2,$ respectively. The mass of gas,adsorbed per gram of adsorbent if the initial pressure is $0.04 \ atm,$ is $........\times 10^{-4} \ g$.
$(\log 3 = 0.4771)$
$(\log 3 = 0.4771)$
Which one of the following equations represents the Freundlich adsorption isotherm?
The surface area of $1 \, g$ of activated charcoal is $1000 \, m^2$. Assuming complete coverage and unimolecular adsorption,if the radius of an ammonia molecule is $10^{-8} \, cm$,then the volume of ammonia adsorbed at $STP$ on $44/7 \, g$ of carbon will be ........ $L$. $(N_A = 6 \times 10^{23})$
