In Langmuir's model of adsorption of a gas on a solid surface 

A

The mass of gas striking a given area of surface is propotional to the pressure of the gas

B

The mass of gas striking a given area of surface is independent of the pressure of the gas

C

The rate of dissociation of adsorbed molecules from the surface does not depend on the surface covered

D

The adsorption at a single site on the surface may involve multiple molecules at the same time

Text Solution

Verified by Experts

The correct Answer is:
A
Langmeric adsorption is unilayer. 
Rate of condensation is a to the product of the pressure of the gas and the fraction of area uncov ered.
