Q. The critical temperatures of $O _{2}, N _{2}, H _{2}$ and $CO _{2}$ and $154.3\, K$, $126\, K , 33.2\, K$ and $304\, K$. The extent of adsorption on tungsten may be highest in case of

Surface Chemistry

Solution:

More easily liquefiable gases, (i.e., higher critical temperature) are readily adsorbed, as van der Waals forces are stronger near the critical temperatures. So, adsorption of $CO _{2}$ will be highest.
