Identify the gas adsorbed by solid to the largest extent at their respective critical temperature.
Options
- AN _ 2(g)
- BO _ 2(g)
- CH _ 2(g)
- DSO _ 2(g)
Correct answer
D. SO _ 2(g)
Step-by-step solution
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 e
