What kind of forces exists between adsorbate and adsorbent in physisor...
Forces in Physisorption:
Physisorption is the process of adsorption in which the adsorbate is held on the surface of the adsorbent by weak van der Waals forces or London forces. These forces are the result of the interaction between the electrons of the adsorbate and the electrons of the adsorbent.
London Forces:
London forces are also known as dispersion forces or induced dipole forces. These forces arise due to the temporary fluctuations in the electron density of the adsorbate and the adsorbent. These fluctuations create temporary dipoles, which in turn induce dipoles in neighboring atoms or molecules. The resulting attractive forces between these dipoles are known as London forces.
London forces are the dominant forces in physisorption because they are the only forces that exist between non-polar molecules, which make up the majority of adsorbates in physisorption.
Conclusion:
Therefore, the correct answer is option 'D', London Force.
