Q
Q: In the van der Waals equation, what do the constants 'a' and 'b' represent?
Solution:
'a' accounts for the attractive forces between molecules, while 'b' accounts for the volume occupied by the gas molecules.
Steps: 5
Show Steps
Step 1: Understand that the van der Waals equation is used to describe the behavior of real gases.
Step 2: Recognize that 'a' is a constant that represents the strength of the attractive forces between gas molecules.
Step 3: Realize that these attractive forces can affect how the gas behaves, especially at high pressures or low temperatures.
Step 4: Understand that 'b' is another constant that represents the volume occupied by the gas molecules themselves.
Step 5: Know that this volume is important because it affects how much space is available for the gas to move around.
