A positive.
Does chemical adsorption have a high adsorption enthalpy?
no
Why physical adsorption is reversible 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
Does physical adsorption have a low adsorption enthalpy?
yes it does...even though physical adsorption is an exothermic reaction, its enthalpy of adsorption is pretty low aroun 20 to 40 kJ/mol
How does adsorption work in reality?
Adsorption is a very similar word to absorption but they are not the same thing really. Adsorption can be used to rid methane smells and such where absorption is what a sponge does to water.

Is adsorption a chemical process in which one substance is taken up by another?
Is adsorption a chemical process in which one substance is taken up by another?
What is adsorption site?
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.
Is adsorption spontaneous?
yes it is
Why adsorption occur?
adsorption is when there are spaces in molecular structure of material. the adsorbed substance is held in these spaces like in sponge.
