Utilize our Van der Waals Equation Calculator to understand real gas behavior. This tool helps compute pressure by accounting for intermolecular forces and finite molecular size, a significant improvement over the ideal gas law. Get precise results for your scientific studies in chemistry and physics.
Formula:
The Van der Waals Equation is given by:
(P + a(n/V)2)(V - nb) = nRT
Where:
- P: Pressure (atm)
- V: Volume (L)
- n: Moles of gas (mol)
- T: Absolute Temperature (K)
- R: Ideal Gas Constant (0.08206 L·atm/(mol·K))
- a: Van der Waals constant correcting for intermolecular attraction (atm·L²/mol²)
- b: Van der Waals constant correcting for finite molecular volume (L/mol)
Our calculator determines P using the rearranged formula:
P = (nRT / (V - nb)) - (a(n/V)2)
