Adsorption is an exothermic process. Explain.

Fertilization is a physico-chemical process. Explain.

Choose the correct alternative : Adsorption is exothermic/endothermic process.

select the correct statement (s) : adsorption is a non - spontaneous process, surface energy deceases during the process of adsorption, adsorption takes place with decrease of entropy, in general adsorption is exothermic process.

"Ultrafiltration is passive process and secretion is an process." Explain.

Adsorption is accompanied by

Adsorption of a gas on the surface of solid is generally accompanied by decrease in entropy, still it is a spontaneous process. Explain.

NCl3 is an endothermic compound while NF3 is an exothermic compound. explain
