Q: What type of surface interaction is primarily involved in the adsorption of gases on metals?
Solution: Gases typically adsorb on metal surfaces through weak van der Waals forces, although some may also involve stronger interactions depending on the gas and metal.
Steps: 4
Step 1: Understand what adsorption means. Adsorption is when gas molecules stick to a surface, like a metal.
Step 2: Identify the forces involved in this sticking process. The main forces are called van der Waals forces, which are weak attractions between molecules.
Step 3: Recognize that while van der Waals forces are common, some gases can interact with metals more strongly, leading to different types of interactions.
Step 4: Conclude that the primary interaction for gas adsorption on metals is through these weak van der Waals forces.
