Yes, physisorption is generally considered a reversible process because it involves weak van der Waals forces or electrostatic interactions between the adsorbate molecules and the adsorbent surface. This means that the adsorbate molecules can easily desorb from the surface under suitable conditions, making physisorption reversible.

Is dissolving salt in water reversible or irreversible?
This is a reversible process.
Is adsorption of oxalic acid on charcoal physisorption or chemisorption?
The adsorption of oxalic acid on charcoal is typically considered to be physisorption. Physisorption involves weak van der Waals forces between the adsorbate (oxalic acid) molecules and the surface of the adsorbent (charcoal). Chemisorption, on the other hand, involves stronger chemical bonds and typically requires more energy.
Why does physisorption decrease with the increase of temperature?
Physisorption is weaker than chemisorption and is typically dependent on van der Waals forces. As temperature increases, the thermal energy disrupts these weak interactions between the adsorbate and the surface, leading to a decrease in physisorption.
Is density reversible?

What is the definition of physisorption?
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.
What is the difference between physisorption and non activated chemisorption?
Physisorption Chemisorption Forces of attraction are vander Waals' forces Forces of attraction are chemical bond forces Low enthalpy of adsorption (20 - 40 k.J/mole) High enthapy of adsorption (200 - 400 k.J/mole) This process is observed under conditions of low temperature This process takes place at high temperatures It is not specific It is highly specific Multi-molecular layers may be formed Generally, monomolecular layer is formed This process is reversible This process is irreversible
Is dissolving salt in water reversible or irreversible?
This is a reversible process.
Is an isothermal process necessarily internally reversible?
No, an isothermal process is not necessarily internally reversible.
Is evaporation a reversible or irreversible separation?
Evaporation is a reversible process.
Is a Bunsen burner on reversible or irreversible?
A Bunsen burner is an object: it is not a process of any kind.
Why does physisorption decreases with increasing temperature?
physisorption is an exothermic reaction.so according to le chatlier's principle,as temperature increases,backward reaction is favoured
Is evaporation reversible change?
Yes it is reversible and the process is called condensation!
Is adsorption of oxalic acid on charcoal physisorption or chemisorption?
The adsorption of oxalic acid on charcoal is typically considered to be physisorption. Physisorption involves weak van der Waals forces between the adsorbate (oxalic acid) molecules and the surface of the adsorbent (charcoal). Chemisorption, on the other hand, involves stronger chemical bonds and typically requires more energy.
What is the difference between reversible and cyclic process?
A reversible process is one that can be undone with no change in entropy of the system and surroundings. A cyclic process is one that starts and ends at the same state, with the system going through a series of state changes. All reversible processes are cyclic, but not all cyclic processes are reversible.
Why physisorption decreases with increase in temperature?
Physisorption is exothermic in nature. Therefore, in accordance with Le-Chateliere's principle, it decreases with an increase in temperature. This means that physisorption occurs more readily at a lower temperature.
Does the entropy of the universe increase when a system undergoes a reversible process?
Yes, the entropy of the universe increases when a system undergoes a reversible process.
