MHT CET Chemistry Question (2026) — Solution

Question

Identify the gas adsorbed by solid to the largest extent at their respective critical temperature.

Options

  1. A. N _ 2(g)
  2. B. O _ 2(g)
  3. C. H _ 2(g)
  4. D. SO _ 2(g)

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 extent. Answer: SO _ 2(g)
