Adsorption of a gas on the surface of solid is generally accompanied by decrease in entropy, still it is a spontaneous process. Explain.

Adsorption is an exothermic process. Explain.

Does the adsorption of a gas on the surface of solid increases or decreases with rise in temperature ?

During the adsorption of a gas on the surface of a solid which of the following is true ?

Read the given passage and answers following questions : In 1916 Langmuir proposed theory of adsorption of a gas on the surface of the solid to be made up of elementary sites each of which would adsorb one gas. It is assumed that all adsorption sites are equivalent and the ability of a gas molecule to get bound to any one site is independent whether or not the neighbouring sites are occupied. Additionally, it is also assumed that dynamic equilibrium exists between adsorbed and non adsorbed gas molecule. Following principles can be obtained from Langmuir adsorption isotherm • The gas adsorbed behaves ideally in a vapour phase. • Only monolayer adsorption takes place. •The surface of the solid is homogeneous. • There are no lateral interactive force between the adsorbate molecule. • The adsorbed gas molecules are localized.
