Which of the following is/are true about Chemisorption?a)The phenomeno...
Chemisorption is a process in which a chemical species is adsorbed onto a solid surface through the formation of chemical bonds. It is different from physisorption, which is the adsorption of species onto a surface through weak intermolecular forces.
a) The phenomenon is characterized by chemical specificity:
Chemisorption is characterized by chemical specificity, meaning that the adsorption of a particular species onto a solid surface depends on the specific chemical nature and structure of the species and the surface. This is because chemisorption involves the formation of chemical bonds between the adsorbate and the surface.
b) Changes in the electronic state may be detectable by suitable physical means:
Chemisorption involves the formation of chemical bonds, which can lead to changes in the electronic state of the adsorbate and the surface. These changes can be detected using physical techniques such as UV spectroscopy, infrared spectroscopy, microwave spectroscopy, electrical conductivity, and magnetic susceptibility. These techniques can provide information about the nature and strength of the chemical bonds formed during chemisorption.
c) Chemisorption can be exothermic or endothermic and the energy changes can vary:
Like chemical reactions in general, chemisorption can be exothermic or endothermic. The energy changes associated with chemisorption can range from very small to very large, depending on the specific adsorbate-surface interaction. The magnitude of the energy changes can provide insights into the strength of the chemical bonds formed and the stability of the adsorbed species on the surface.
d) The elementary step in chemisorption often involves an activation energy:
The elementary step in chemisorption often involves an activation energy, which is the minimum energy required for the reaction to occur. This activation energy is necessary to overcome the energy barrier associated with the breaking and formation of chemical bonds. Once the activation energy is surpassed, the chemisorption process can proceed.
In summary, all of the given options are true about chemisorption. Chemisorption is characterized by chemical specificity, changes in the electronic state can be detected by suitable physical means, the energy changes can vary from small to large, and the elementary step often involves an activation energy.
