At relatively high pressure, van der Waal's equation reduces to

A

`pV=RT`

B

`pV=Rt-a/V`

C

`pV=RT-a/(V^(2))`

D

`pV=RT+pb`

Text Solution

Verified by Experts

The correct Answer is:
D
At high pressure, the pressure correctioin for 1 mole of gas is negligible.
`:.a/(V^(2))=0`
However, the volume correction cannot be neglected. Hence vander Walls' equation reduces to `(p+0)(V-b)=RT` (For 1 mole)
`pV-pb=RT`
`:.pV=RT+pb`
