Web(vi) Chemisorption results into unimolecular layer. Sometimes these two processes occur simultaneously and it is not easy to ascertain the type of adsorption. A physical adsorption at low temperature may pass into chemisorption as the temperature is increased. For example, dihydrogen is first fadsorbed on nickel by van der Waals’ forces. WebDec 11, 2024 · Chemisorption is highly specific in nature whereas physisorption is not specific. iii Chemisorption results into unimolecular layer whereas physisorption results into multimolecular layers. iv Chemisorption is irreversible in nature whereas physisorption is reversible in nature follow me please

Chemisorption - an overview ScienceDirect Topics

WebThe chemisorption process is exothermic and thus results in an increase in temperature. The process is irreversible. It is characterised by the chemical bonds between the gas … WebLigand exchange and chemisorption are the names given to the ‘specific’ sorption reactions for anions and cations, respectively. Specific sorption differs from ion exchange … WebThe degree of chemisorption that occurs increases as the temperature rises. Because of the weak Van Der Waal forces, physisorption produces a multimolecular layer. Because chemisorption is created by covalent bonds, which are extremely strong bonds, it results in a unimolecular layer. The activation energy of physical adsorption is lower. high table round wooden folding
