Question

As per Langmuir model of adsorption of a gas on a solid surface.

• A. The mass of gas striking a surface area is independent of the pressure of the gas
• B. The adsorption can be multilayer.
• C. The rate of desorption does not depend on the pressure.
• D. The rate of desorption does not depend on the surface are adsorbed.

Answer 1

Answer: (C)

The rate of desorption does not depend on the pressure.

In Langmuir's model of adsorption of a gas on solids surfaces. The adsorption at a single site on the surface may invoice multiple molecules at the ame time. The mass of gas striking at a given area of surface is independent of the pressure of the gas.
