compare 3 laws: van dear waals, redlich kwong equation, viral equation. which of the law do you think will model reality best for N2 gas? And which of the law will best reality model for He gas?

Expert Solution

Vander Waals equation

The Van der Waals equation is :

is molar volume, substance-specific constants and

Also written as

Redlich-Kwong equation

It is primarily due to its relatively simple form and While superior to the van der Waals equation of state

Virial equation of state[edit]

Main article: Virial expansion

virial equation is important due to the resion it can be derived directly from statistical mechanics

This expression is good for non-polar gases.

N₂ is a nonpolar gas so virial equation model is most appropriae for N₂ gas.

He is a noble gas which has vander wall bonding He, so the vander wall equation model is best suited for the He gas

The van der Waals equation for 1 mole of gas is given by (p +av-2)(v - b) = RT. In general, curves of p versus v forvarious values of T exhibit a maximum and a minimum at the twopoints where (δp/δv)T = 0. The maximum and minumum coalesceinto a single point on that curve where(δ2p/δv2)T = 0 inaddition to (δp/δv)T = 0. This point is calledthe "critical point" of the substance and its temperature,pressure, and molar volume are denoted by...
