Web1. If reactants are added, the equilibrium will shift to the right 2.to remove the added reactants Which Cl or Br has higher boiling point and why? 1.Bromine 2.Because bromine is a bigger atom than chlorine, therefore it will have stronger VDW forces Chlorine is used to destroy bacteria, why is it used in pools even though it is toxic? WebThe vdW force originates from quantum mechanics, acts between atoms, molecules and surfaces, and is composed of induction force, orientation force, and dispersion force. The Hamaker technique is the most commonly used to determine the vdW force/energy between two surfaces ( Hamaker, 1937 ).

WebApr 8, 2024 · The Van Der Waals equation is a state that shows two properties of gases, such as the excluded volume of real gases and its attractive forces. It gets expressed as: (P+n2a/V2) (V-nb)= nRT Where a = magnitude of attraction within molecules/ atoms And, b = excluded volume.

WebJan 30, 2024 · Van der Waals forces are driven by induced electrical interactions between two or more atoms or molecules that are very close to each other. Van der Waals interaction is the weakest of all intermolecular attractions between molecules. However, with a lot of Van der Waals forces interacting between two objects, the interaction can be very strong.
