Adsorption is an exothermic process, because during adsorption

Question

Adsorption is an exothermic process, because during adsorption (A) surface energy increases (B) surface energy decreases (C) surface energy remains same (D) residual forces of attraction increase

Tardigrade Admin · Accepted Answer

During adsorption, there is always a decrease in residual forces of the surface, i.e., there is decrease in surface energy which appears as heat, therefore adsorption is an exothermic process.

Q. Adsorption is an exothermic process, because during adsorption

surface energy increases

surface energy decreases

surface energy remains same

residual forces of attraction increase

During adsorption, there is always a decrease in residual forces of the surface, i.e., there is decrease in surface energy which appears as heat, therefore adsorption is an exothermic process.
