Identify FALSE statement regarding adsorption from following.
Identify FALSE statement regarding adsorption from following.
It takes place due to unbalanced forces acting on the surface of solid or liquid.
During adsorption surface energy of adsorbent increases.
It is caused by van der Waals forces.
It is an exothermic process.
Solution
During adsorption, surface energy decreases because the adsorbate molecules interact with the adsorbent and stabilize the system. This leads to a reduction in free surface energy.
