In physical adsorption,the gas molecules are held on a solid surface by

When $H_2S$ gas is passed through an arsenious oxide solution,an arsenious sulphide sol is formed. The charge on the particles is due to the adsorption of .......

Froth flotation process for the concentration of ores is an illustration of the practical application of

Regarding the adsorption of a gas on the surface of a solid,which of the following is $NOT$ true?

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):

At high pressure,the entire surface is covered by a unimolecular layer of gas,which follows ......... order.
