Question

derive and explain vander waal's equation of state

Answer 1

vanderwall proposal and approximate equation of state which involves the intermolecular interactions that contribute to the derivations of a gas from perfect gas law
volume correction:
the repulsive interactions between two molecules cannot allow them to come closer than a certain distance.
For gas molecules the available volume for free travel is not the volume of container "V" but reduced to an extent proportional to the number of molecules and the volume of each exclude
therefore p=
$\frac{nrt}{v - nb}$
'b' is volume constant

Answer 2

Hey mate ^_^

=======
Answer:
=======

=> Real gas deviates from ideal gas behaviour as there are forces of attraction and repulsion between the molecules of a gas.

=> At high pressure, while striking the walls of a container, the molecules of a gas are dragged back by other molecules due to the existing force of attraction.

=> Therefore, the pressure exerted by the gas is lower than the pressure exerted by an ideal gas.
