At high pressure , the van der Waals equation is reduced to

A

`pV = nRT`

B

`(p + (n^(2)a)/(V^(2)))V = nRt`

C

`p + (n^(2)a)/(V^(2)) = nRt`

D

`p(V - nb) = nRt`

Text Solution

Verified by Experts

The correct Answer is:
D
When the pressure is high , the volume occupied by the gas is low. Hence, the constant `b` cannot be neglected relative to small volume occupied by the gas is low. Hence, the constant `b` cannot be neglected relative to small volume. However , the term `an^(2)//V^(2)` can be neglected relative to large pressure.
