The substance that increases the speed of a chemical reactions is called

Adsorption is surface phenomenon, while absorption concerns with the whole mass of the absorbent. In adsorption, the substance is only retained on the surface and does not go into the bulk or interior of the solid or liquid. Absorption implies that substance is uniformly distributed throughout the body of the solid or liquid. In adsorption, the concentration of the adsorbed molecules is always greater in the immediate vicinity of the surface tlian in the free phase. Absorption involves bulk penetration of the molecules into the structure of the solid or liquid by some process of diffusion. Adsorption is a rapid process and equilibrium is attained in a short time. In absorption the equilibrium takes place slowly. Such substance is said to be sorbed and the phenomenon is known as sorption. What is phenomenon of adsorption.

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. Who proposed the theory of adsorption of a gas on the surface of the solid ?
