What is the equation of state of real gas?
The equation of state for a real gas is typically described by the Van der Waals equation, which accounts for the volume occupied by gas molecules and the attractive forces between them. The equation is: (P + a(n/V)^2)(V - nb) = nRT, where P is pressure, V is volume, n is amount of substance, a and b are Van der Waals constants, R is the ideal gas constant, and T is temperature.
What is the significance of the real gas equation?
For most applications, such a detailed analysis is unnecessary, and the ideal gas equation is another two-parameter equation that is used to model real gases.

How to solve using the van Der Waals equation to estimate the pressure exerted by 1.000 mole Cl2 in 22.41 L at 273K. Compare it to an ideal gas?
First, calculate the van der Waals constants (a and b) for Cl2. Then, substitute these values, along with the given values (n = 1.000 mol, V = 22.41 L, and T = 273 K), into the van der Waals equation to find the pressure. Finally, compare the calculated pressure with that predicted by the ideal gas equation (PV = nRT) for the same conditions.
How does vander waals attraction effect on boiling point?
Van der Waals forces, which are weak attractive forces between molecules, can increase the boiling point of a substance. This is because the attraction between molecules makes it more difficult for them to escape into the gas phase. Therefore, substances with stronger van der Waals forces typically have higher boiling points.
Pvt relationship of non ideal gases?
In a private relationship for non-ideal gases, the behavior of gases is described by the Van der Waals equation, which accounts for the volume occupied by gas molecules and intermolecular forces. This equation provides a more accurate prediction of gas behavior at high pressures and low temperatures compared to the ideal gas law.

Why vander waals equqtion is applicable to real gasas?
[P + a(n/V)2] (V - nb) = nRT As you see this is a correction method for gasses other than ideal. Gasses at high pressure and high/low temperature. The ideal gas equation makes assumptions that are not always applicable to real word conditions as to gasses.

What is the virial expansion of the van der Waals equation of state?
The virial expansion of the van der Waals equation of state is a mathematical representation that describes the behavior of real gases. It is used to account for the interactions between gas molecules, which are not considered in the ideal gas law. The expansion includes higher-order terms beyond the ideal gas law to better predict the behavior of gases under different conditions.
How does vander waals attraction effect on boiling point?
Van der Waals forces, which are weak attractive forces between molecules, can increase the boiling point of a substance. This is because the attraction between molecules makes it more difficult for them to escape into the gas phase. Therefore, substances with stronger van der Waals forces typically have higher boiling points.
What is the physical significance of vander walls constants a and b?
Vander Waals constant 'a' represents the attraction between gas molecules, while constant 'b' represents the volume occupied by the gas molecules. 'a' is related to the cohesive forces between molecules, while 'b' is related to the excluded volume due to the size of the molecules. These constants help account for deviations from ideal gas behavior in real gases.

The real gas formula used to calculate the behavior of gases under non-ideal conditions is the Van der Waals equation.
How is the virial expansion used to describe the behavior of real gases, particularly in the context of the van der Waals equation of state?
The virial expansion is a mathematical tool used to describe the behavior of real gases by accounting for interactions between gas molecules. In the context of the van der Waals equation of state, the virial expansion helps to correct for deviations from ideal gas behavior by incorporating terms that account for molecular size and intermolecular forces. This allows for a more accurate description of gas behavior under non-ideal conditions.
