Question: The compressibility factor for a real gas at high pressure is :...
The compressibility factor for a real gas at high pressure is :
A
1 + RT/pb
B
1
C
1 + pb /RT
D
1 –pb/RT
Answer
1 + pb /RT
Explanation
Solution
(P+V2a)(V−b)=RT
at high pressure can be neglected.
PV – Pb = RT
PV = RT + Pb
RTPV = 1 +RTPb
Z =1 + RTPb ; Z > 1 at high pressure
