The compressibility factor for a real gas at high pressure is `:`

A

`1-pb//RT`

B

`1+RT //pb`

C

1

D

`1+Pb//RT`

Text Solution

Verified by Experts

The correct Answer is:
D
van der Waals. equation is `:`
`( p + ( a )/( V^(2)))(V -b) = RT`
At high pressure , `(a)/(V^(2))` can be neglected so that
`p(V -b) = RT`
`pV -pb = RT`
or `( pV)/( RT) - ( pb)/( RT) = 1 `
or `( pV)/(RT) = 1+ ( pb)/(RT) :. z = 1 + ( pb)/( RT)`
