The catalytic polymerization of a monomer, M says, CH2 = CHX here, X = halogen. The following steps are involved in this process:The initiator molecule I yields a free radical...
The diffusion of a substance across a plane perpendicular to the direction of motion is given by Fick’s first law of...
What is Osmotic pressure? The extra pressure applied on the solution to stop the flow of solvent through the semipermeable membrane is called osmotic...
Staudinger proposed this method. Accurate measurement of absolute viscosity being difficult, it is convenient to measure relative viscosity, ηrel, defined...
In 1938, Brunauer, Emmett and Teller proposed a model called the BET isotherm for multilayer adsorption. According to them, the first step in adsorption...
The Langmuir theory of adsorption only applies to forming a monomolecular layer of gas molecules on a solid surface. The theory of adsorption proposed in 1938 by Brunauer, Emmett and Teller is known as the BET theory. They assume...
Many adsorption isotherms of gases on various adsorbents at different temperatures have now been determined. It can be divided into five different types, as shown in the figure. In each case, p0 represents the saturation pressure...
In 1916 Langmuir proposed his theory of a gas’s adsorption on a solid’s surface. The solid’s surface is made up of elementary sites, each of which adsorbs one gas molecule.
