Question

Which will be adsorbed more readily on the surface of charcoal and why?

NH₃ or CO₂

Answer 1

NH₃ (ammonia) will be adsorbed more readily on the surface of charcoal than CO₂ (carbon dioxide).

Reason:

1. NH₃ is more easily liquefiable compared to CO₂.
2. Greater liquefaction tendency signifies stronger intermolecular forces.
3. Stronger intermolecular forces enhance the adsorption on the charcoal surface.
4. Therefore, ammonia interacts more strongly with charcoal, resulting in greater adsorption.
