Question

What are the factors effective adsorption of gases on solids?

Answer 1

Answer:

Explanation:

1. Nature of gases: Ease is liquefication more is gas adsorbed.
2. The surface area of adsorbent: More the surface area more gas is adsorbed.
3. Temperature: Physisorption increases with a decrease in temperature while chemisorption increases with an increase in temperature.
4. Pressure: It affects only physisorption if pressure increase amount of gas adsorbs also increase.

Answer 2

Answer:

Nature of adsorbent

The adsorption of the gas depends on the nature of the adsorbent. A gas can be adsorbed on different absorbent surfaces in different amounts. For example, Hydrogen is weakly adsorbed on the alumina surface whereas it is strongly adsorbed on the nickel surface under certain conditions.
