Factors affecting the rate of adsorption?

Answer 1

The adsorbtion of methyl blue by activated carbon increases with increasing temperature. Not sure about other types of adsorbtion.

Answer 2

They are as follows:

1)Temperature

2)Pressure

3) Surface of adsorbent

4) Nature of adsorption process (either chemi-adsorption of phsi-adsorption)

that all these are the major factors affecting the rate of adsorption.

Answer 3

Most adhesive material is in a semi-liquid form which dries up into a solid, if you use heat on an adhesive material and place it where needed, then freeze it you get a faster working glue. Of course freezing at very low temperatures could also solidify the adhesive and make it useless.

Answer 4

The rate of adsorption is influenced by factors such as surface area of the adsorbent, concentration of the adsorbate in the solution, temperature, polarity of the adsorbate and adsorbent, and the presence of impurities or competing adsorbates. These factors affect the driving forces for adsorption and the interactions between the adsorbent and adsorbate molecules, ultimately impacting the rate at which adsorption occurs.

Answer 5

phyisorption takes place at low temperature. at 4k which is the b.p of He, any thing gets physisorbed.
