Q: What is the effect of increasing temperature on physisorption?
Solution:
Increasing temperature generally decreases physisorption because it disrupts the weak van der Waals forces.
Steps: 6
Show Steps
Step 1: Understand what physisorption is. It is the process where molecules stick to a surface through weak forces called van der Waals forces.
Step 2: Know that temperature is a measure of how much energy the molecules have. Higher temperature means more energy.
Step 3: Realize that when temperature increases, the energy of the molecules also increases.
Step 4: Understand that the increased energy can cause the molecules to move more vigorously.
Step 5: Recognize that the weak van der Waals forces that hold the molecules to the surface can be disrupted by this increased movement.
Step 6: Conclude that as temperature increases, the physisorption decreases because the molecules are less likely to stay attached to the surface.
