Behaviour of Real Gases

The pressure exerted by 1 mole of CO₂ at 273 K, is 34.98 atm. Assuming that volume occupied by CO₂ molecules is negligible, the value of van der Waals' constant for attraction of CO₂ gas is :

In Van der Waal’s equation of state for a non-ideal gas, the term that accounts for intermolecular forces is:

Van der Waal’s real gas, act as an ideal gas, at which conditions ?

At which one of the following temperature – pressure conditions the deviation of a gas from ideal behaviour is expected to be minimum ?

When deviation is more in the behaviour of a gas from the ideal gas equation PV = nRT ?

The two assumptions of kinetic molecular theory of gases do not hold good at high _____ or low temperature.

Identify the postulate of kinetic molecular theory of gases which does not hold good under all conditions.

Identify the postulate of kinetic molecular theory of gases which does not hold good under all conditions.

Write the postulates of kinetic theory of gases which do not hold good under all the conditions of temperature and pressure.

According to kinetic theory, the gas particles occupy a negligible fraction of the total volume of the gas. This assumption is responsible for the volume correction in the ideal gas equation of real gases.

Mentions two assumptions of kinetic theory of gases, which are responsible for the volume correction in the ideal gas equation of real gases.

Explain the factors responsible for the volume correction in the ideal gas equation of real gases.

For an ideal gas, the compressibility factor is

For one mole of a van der Waals' gas, the compressibility factor $Z=\left(\frac{pV}{RT}\right)$ at a fixed volume will certainly decrease, if
