Which from following gases is adsorbed to greater extent if adsorbent remains same at similar conditions of temperature and pressure?

Step-by-step solution

The extent of adsorption in physisorption depends on the ease of gas liquefaction, which correlates directly with critical temperature T_c . The critical temperatures are: H ₂ at 33 K, N ₂ at 126 K, O ₂ at 155 K, and SO ₂ at 430.65 K. Increasing order of T_c is H ₂ SO ₂ has the highest critical temperature and will thus be adsorbed most extensively. Final answer: B
