If x is amount of adsorbate and m is amount of adsorbent, which of the following relations is not related to adsorption process?
x / m= f(p) at constant T
x / m= f(T) at constant p
p=f(T) at constant (x / m)
Freundlich isotherm graph -
This curve indicate that at fixed pressure there is a decrease in physical adsorption with increase in temperature
- wherein
Adsorption from solution phase -
- wherein
Freundlich's equation approximately describe the behaviourof adsorption from solution with a difference that instead of pressure concentration is taken into account.
Option 1)
x / m= f(p) at constant T
This is incorrect answer
Option 2)
x / m= f(T) at constant p
This is incorrect answer
Option 3)
p=f(T) at constant (x / m)
This is incorrect answer
Option 4)
This is correct answer
