Which of the following is less than zero during adsorption?

Adsorption is exothermic.      = -veDue to Adsorption of gases on solids (or) dissolved solute particles of a solution on solid surface,randomness decreases. =-veThe process of adsorption is spontaneous.    =-veAt low Temperatures, magnitude of > TFrom  = - T   ;       will be -vethe process is spontaneous
