Question

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

Tardigrade Admin · Accepted Answer

(P+(a/V2))(V-b) = RT at high pressure (a/V2) can be neglected PV - Pb = RT PV = RT + Pb (PV/ textRT ) = 1 + (Pb/RT) Z = 1+(Pb/RT) ; Z > 1 at high pressure

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

$1 + RT / P b$

$1$

$1 + P b / RT$

$1 - P b / RT$

$(P + \frac{a}{V ^{2}}) (V - b) = RT$
at high pressure $\frac{a}{V ^{2}}$ can be neglected
$P V - P b = RT$
$P V = RT + P b$
$\frac{P V}{RT} = 1 + \frac{P b}{RT}$
$Z = 1 + \frac{P b}{RT}; Z > 1$ at high pressure

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

1+RT/Pb

1

1+Pb/RT

1−Pb/RT

(P+V2a​)(V−b)=RT at high pressure V2a​ can be neglected PV−Pb=RT PV=RT+Pb RTPV​=1+RTPb​ Z=1+RTPb​;Z>1 at high pressure

$1 + RT / P b$

$1$

$1 + P b / RT$

$1 - P b / RT$

$(P + \frac{a}{V ^{2}}) (V - b) = RT$
at high pressure $\frac{a}{V ^{2}}$ can be neglected
$P V - P b = RT$
$P V = RT + P b$
$\frac{P V}{RT} = 1 + \frac{P b}{RT}$
$Z = 1 + \frac{P b}{RT}; Z > 1$ at high pressure
