What is the effect of temperature on physisorption?
Increases with temperature
Decreases with temperature
No effect
Depends on the adsorbate
Physisorption typically decreases with increasing temperature because the kinetic energy of the molecules increases, overcoming the weak van der Waals forces.

Q: What is the effect of temperature on physisorption?
Solution: Physisorption typically decreases with increasing temperature because the kinetic energy of the molecules increases, overcoming the weak van der Waals forces.
Steps: 4
Step 1: Understand what physisorption is. It is a type of adsorption where molecules stick to a surface through weak forces called van der Waals forces.
Step 2: Know that temperature affects the energy of molecules. As temperature increases, the kinetic energy of the molecules also increases.
Step 3: Realize that with higher kinetic energy, molecules move faster and can overcome the weak forces holding them to the surface.
Step 4: Conclude that as temperature increases, physisorption decreases because the molecules are more likely to detach from the surface.
