What kind of forces exists between adsorbate and adsorbent in physisorption?
Physisorption is defined as adsorption in which force between adsorbate and adsorbent is physical van der Waals force also known as London force.
Adsorbate is represented by which spheres in the following diagram.
So Black molecules should be adsorbate.
Which phenomenon is represented by the following diagram?
Adsorption is a surface phenomenon where concentration of the molecules, is more on the surface than in the core.
Which of the following statement is correct about Langmuir’s adsorption?
Why shoes, purses and leather items have silica gel pouches kept in them?
Solids, particularly in a finely divided state, have a large surface area and so silica gel is a good adsorbent and keeps the leather dry and free of moisture.
The relation between extent of adsorption (x/m) and pressure at constant temperature is called as:
Freundlich adsorption isotherm gives an empirical relationship between the quantity of gas adsorbed by the unit mass of solid adsorbent and pressure at a specific temperature.
Which of the following is the reason for adsorption?
There is an unbalanced attractive force of adsorbent are responsible for attracting the adsorbate particles on its surface.
Which of the following options are correct?
Adsorption is the phenomenon in which a substance:
Freundlich adsorption isotherm is a plot between:
The plot between the extent of adsorption (x/m) against the pressure of gas (P) at constant temperature (T) is called the adsorption isotherm.
