Adsorption increases with temperature.

Vedclass · Answer

(C) Chemisorption involves the formation of chemical bonds between the adsorbate and the adsorbent,which requires an activation energy. Therefore,initially,the rate of adsorption increases with an increase in temperature. The provided graph shows the variation of the extent of adsorption $(x/m)$ with temperature $(T)$ at a constant pressure $(p)$,where the adsorption first increases and then decreases,which is characteristic of chemisorption.

Gas	Critical Temperature
$A$	$304 \ K$
$B$	$630 \ K$
$C$	$200 \ K$
$D$	$540 \ K$
