Explain the pressure and volume corrections in ideal gas equation?

1.	Explain the pressure and volume corrections in ideal gas equation?
Answer» At low temperature and high pressure intermolecular attractions cannot be neglected, the observed pressure P is smaller than the ideal pressure Pi. Therefore, Pi = P + p = P + an²/V₂. As volume of gas molecules is not negligible as compared to total volume of the gas the ideal volume Vi is smaller than the observed volume. Therefore, Vi = V + v = V - nb.

Answer»

At low temperature and high pressure intermolecular attractions cannot be neglected, the observed pressure P is smaller than the ideal pressure Pi.

Therefore, Pi = P + p = P + an²/V₂.

As volume of gas molecules is not negligible as compared to total volume of the gas the ideal volume Vi is smaller than the observed volume. Therefore, Vi = V + v = V - nb.
