(A) High pressure
(B) Intermediate pressure
(C) Low temperature
(D) None of these

Answer 1

Answer:

Options c

Explanation:

Because low pressure

Answer 2

Langmuir isotherms holds at low pressure but fails at high pressure.

Option - A

Explanation:

• The Langmuir isotherm was proposed in the year of 1932 by Irving Langmuir.
• The Langmuir adsorption is the having some assumptions on adsorbant that behaves as ideal gas at the isothermal conditions.
• Langmuir isotherm is the semi-empirical isotherm that derived from the "proposed kinetic mechanism".
• Langmuir adsorption isotherm is the chemical adsorption that fails at high pressure because the adsorbed mass which reaches a certain constant value while the surface which is adsorbed, that is covered by the unimolecular layer of gases completely.
