Q. In Langmuir’s model of adsorption of a gas on a solid surface
A) The rate of dissociation of adsorbed molecules from the surface does not depend on the surface covered
B) The adsorption at a single site on the surface may involve multiple molecules at the same time
C) The mass of gas striking a given area of surface is proportional to the pressure of the gas
D) The mass of gas striking a given area of surface is independent of the pressure of the gas
Explanation
(c)
The adsorption of a gas is directly proportional to the pressure of the gas.
