Question

What is vanderwaals gas equation and it's important

Answer 1

Answer:

The van der Waals equation is an equation of state that corrects for two properties of real gases: the excluded volume of gas particles and attractive forces between gas molecules. The van der Waals equation is frequently presented as : [latex](P + \frac{an^2}{V^2})(V-nb) = nRT[/latex] .

It is the measure of the magnitude of attractive forces between the molecules of a gas. Larger the value of 'a', larger will be the intermolecular force of attraction.

The ideal gas law treats the molecules of a gas as point particles with perfectly elastic collisions. This works well for dilute gases in many experimental circumstances.
