Which statements among the following are correct?
(i) Freundlich isotherm fails at high pressure of the gas.
(ii) for both physical and chemical adsorption.
(iii) Physical adsorption is non-selective.
(iv) Chemical adsorption is reversible, where as physical adsorption is irreversible.
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
According to the Freundlich isotherm, thevariation of extent of adsorption (x/m) with pressure (P) was given mathematically by Freundlich.Where n can take any whole number value which depends uponthe nature of adsorbate and adsorbent. The above relationship is also called…
