adsorption is when there are spaces in molecular structure of material.
the adsorbed substance is held in these spaces like in sponge.
Yes, the adsorption capacity of an adsorbent is influenced by its porosity. A higher porosity provides more surface area for adsorption to occur, resulting in a greater adsorption capacity. Therefore, materials with higher porosity generally exhibit higher adsorption capabilities.
no
Structure can provide a larger surface area for adsorption to occur, allowing more molecules to come into contact with the adsorbent material. It can also create smaller pores or channels that can trap molecules more effectively. Additionally, a well-defined structure can provide more active sites for molecules to bind to, increasing the efficiency of the adsorption process.
adsorption is processs of accumulation of liquid/gases on solid surface. reversible adsorption is seen in physical adsorption where increase in pressure increases the adsorption and decrease in pressure decrease adsorption of molecules to surface that is desorption takes place
In adsorption, Gibbs free energy decreases because the adsorbate molecules are attracted to the surface of the adsorbent, reducing the overall energy of the system. This leads to a more stable configuration with a lower free energy. The decrease in Gibbs free energy indicates that the adsorption process is spontaneous at a given temperature and pressure.
Yes, the adsorption capacity of an adsorbent is influenced by its porosity. A higher porosity provides more surface area for adsorption to occur, resulting in a greater adsorption capacity. Therefore, materials with higher porosity generally exhibit higher adsorption capabilities.
Surface tension and surface adsorption occur only on the surface of a substance. Surface tension is the tendency of a liquid surface to shrink into the minimum surface area possible, while surface adsorption is the accumulation of molecules at the surface of a material.
no
Physisorption is the reversible adsorption of molecules onto a surface due to weak van der Waals forces. It involves physical interactions rather than chemical bonds, and can occur in processes such as gas adsorption on solid surfaces.
Yes, physical adsorption typically has a low adsorption enthalpy due to weak van der Waals forces between the adsorbate and adsorbent. These interactions are reversible and non-specific, leading to lower enthalpies compared to chemical adsorption.

An adsorption site is a location on a surface where molecules or particles can adhere or bind due to attractive forces. It is where adsorption occurs, where a substance accumulates on the surface of another material. Adsorption sites are important in processes like catalysis, gas separation, and water treatment.
In reality, adsorption is a process where molecules in a gas or liquid adhere to the surface of a solid. This occurs due to the attractive forces between the molecules and the solid surface. Adsorption is used in various applications such as purifying gases, wastewater treatment, and catalysts.
