Vedclass · Answer

(A) According to the Freundlich adsorption isotherm,the adsorption of a gas on a solid surface follows these stages with increasing pressure: $1$. At low pressure,the extent of adsorption $(x/m)$ is directly proportional to pressure $(P^1)$,which is a fast process. $2$. At intermediate pressure,it is proportional to $P^{1/n}$ (where $n > 1$),showing a slower rate of increase. $3$. At high pressure,the surface becomes saturated,and adsorption becomes independent of pressure $(P^0)$. Thus,the correct sequence is: Fast $	o$ slow $	o$ independent of the pressure.

The adsorption of a gas on a solid surface varies with the pressure of the gas in which of the following manners?
