Van der Waals equation Formula
We know about the ideal gas equation
pV = nRT
In ideal gas equation said that the force of attraction is zero and and has negligible Volume.
But in van der Waals give two correction of volume and pressure. According to van der Waals it assume that
- The force of attraction between gases molecule are negligible at any condition but not zero.
- In the volume occupied in the gaseous molecule has also own volume.
Van der Waals equation is obtained from modification of ideal gas equation.
a and b = van der Waals constant
P = pressure
V = Volume
n= number moles
T = Temperature
R = universal gas constant
