Vedclass · Accepted Answer

All relationships are correct.

Vedclass · Answer

(A) According to the Freundlich adsorption isotherm,the relationship between the extent of adsorption $(x/m)$ and pressure $(P)$ is given by $x/m = k \cdot P^{1/n}$,where $n > 1$.
$1$. At low pressure,$1/n \approx 1$,so $x/m = k \cdot P^1$,which means it is directly proportional to pressure.
$2$. At intermediate pressure,$x/m = k \cdot P^{1/n}$,where $0 < 1/n < 1$.
$3$. At high pressure,$1/n \approx 0$,so $x/m = k \cdot P^0 = 	ext{constant}$,meaning it becomes independent of pressure.
Comparing these with the given statements,all three relationships are correct representations of the Freundlich isotherm under the specified conditions.

Gas	Critical temperature $(K)$
$He$	$5.2$
$CH_{4}$	$190$
$CO_{2}$	$304.2$
$NH_{3}$	$405.5$
