WebBy adding corrections for interparticle attractions and particle volumes to the ideal gas law, we can derive a new equation that more accurately describes real gas behavior. This equation, known as the van der Waals equation, can be used to calculate the properties of a gas under non-ideal conditions. Created by Sal Khan. WebApr 8, 2024 · Van Der Waals equation is an equation that is used to relate the relationship existing between the pressure, volume, temperature, and amount of real gases. For a real gas containing ‘n’ moles, the real gas equation derivation is as follows. (P + \[\left ( \frac{an^{2}}{V^{2}} \right )\] ) V−nb = nRT.
