Question
Which will be adsorbed more readily on the surface of charcoal and why? NH3 or O2?
Solution
1. The gases having low critical temperature are adsorbed slowly, while gases with high critical temperature are adsorbed readily.
2. Among CO2, and NH3, NH3 will be more readily adsorbed on the surface of the charcoal. This is because the critical temperature of ammonia gas is quite high than the CO2. Hence, it easily combines with the materials than the CO2 whether it is solid, liquid, or any gases.
