Question
Identify the gas adsorbed by solid to the largest extent at their respective critical temperature.
Identify the gas adsorbed by solid to the largest extent at their respective critical temperature.
D. SO _ 2(g)
The extent of adsorption of a gas on a solid surface depends on the strength of intermolecular forces. Gases with higher critical temperatures have stronger van der Waals forces of attraction and are more easily liquefiable, leading to a greater extent of adsorption. The critical temperatures of the given gases are approximately: H _ 2 33 K N _ 2 126 K O _ 2 154 K SO _ 2 430 K Since SO _ 2 has the highest critical temperature among the given options, it has the strongest intermolecular forces and is adsorbed to the largest extent. Answer: SO _ 2(g)
