A) chemical forces
B) electrostatic forces
C) gravitational forces
D) van der Waals' forces
Correct Answer: D
Solution :
In physical adsorption, reactant molecules are adsorbed on surface by weak van der Waals' forces. Physical adsorption is multilayer, non-directional and non specific and exothermic. It does not require activation energy. An increase in temperature decreases physical adsorption.You need to login to perform this action.
