Under critical conditions, the compressibility factor for a gas is .

A

`(3)/(8)`

B

`(8)/(3)`

C

`1`

D

`(1)/(4)`

Text Solution

Verified by Experts

The correct Answer is:
A

`V_(C )= 3b`
`P_(C )= a//27b^(2)`
`T_(C )= 8a//27Rb`
`Z_(C )=(P_(C )V_(C ))/(TC)=((a//27b^(2))(3b))/(R(8a//27Rb))=(3)/(8)`
