The correct Answer is:
To determine which gas shows the least adsorption on a definite amount of charcoal, we can analyze the critical temperatures of the provided gases: H₂, CH₄, CO₂, and SO₂. ### Step-by-Step Solution: 1. **Understanding Adsorption**: - Adsorption is the process where molecules from a gas or liquid phase adhere to the surface of a solid (adsorbent). The extent of adsorption is influenced by the nature of the gas and its ability to be liquefied. 2. **Critical Temperature**: - The critical temperature (T_c) of a substance is the temperature above which it cannot exist as a liquid, regardless of the pressure applied. Gases with higher critical temperatures are more easily liquefied and tend to be adsorbed more on surfaces like charcoal. 3. **Given Data**: - The critical temperatures of the gases are as follows: - H₂: 33 K - CH₄: 190 K - CO₂: 304 K - SO₂: 630 K 4. **Analyzing Critical Temperatures**: - Among the gases listed, H₂ has the lowest critical temperature (33 K). This means that H₂ is the least easily liquefiable gas compared to the others. 5. **Conclusion**: - Since the extent of adsorption is inversely related to the critical temperature, the gas with the lowest critical temperature (H₂) will show the least adsorption on charcoal. Therefore, H₂ is predicted to show the least adsorption. ### Final Answer: - The gas that shows the least adsorption on a definite amount of charcoal is **H₂ (Hydrogen)**. ---

Only the surface atoms in an adsorbent play an active role in adsorption. These atoms possess some residual force such as van der Waals forces and chemical forces. In the process of adsorption. Weak adsorbate is substituting by strong adsorbete. Activated charcoal used in the gas mask is already exposed to the atmospheric air, so gases and water vapours in air are adsorbed on its surface. When the mask is exposed to chlorine atmosphere, the gases are displaced by chlorine. In general, easily liquefiable gases such as CO_(2),NH_(3),Cl_(2), and SO_(2) are adsorbed to a greater extent than the elemental gases, e.g., H_(2),N_(2),O_(2), He, etc. Which of the following gases will substitute O_(2) from adsorbed charcoal?
