Study Notes
Real Gases
-
Real gases deviate from ideal gas behavior, unlike ideal gases which follow the equation PV = nRT.
-
The compressibility factor, Z, is used to account for this deviation.
-
PVm = RT
-
Z = RT / PVm = Vm / Videal = P / Pideal
-
Boyle temperature (TBoyle) is the temperature at which the properties of a real gas match those of an ideal gas as pressure approaches zero (P → 0).
-
Determining TBoyle:
- For the Van der Waals gas, determine Z.
- Substitute 1/Vm by y.
- Calculate (∂Z/∂y)T.
- Set (∂Z/∂y )T|y=0 to zero and calculate TBoyle.
-
Van der Waals equation of state: PVm = RT + (a/Vm2) – (b/Vm).
- The other method using series: 1/(1-x) = Σ xn, |x| < 1
- For Van der Waals gas, P = RT / (Vm - b) – a / Vm2
Condensation
-
Condensation is the process where a substance changes from a gaseous state to a liquid state.
-
Critical point properties:
- Pc = RTc / Vm,c -b - a / Vm,c2
- ∂Pc / ∂Vm,c =0
- ∂2Pc/ ∂Vm,c2= 0
-
Calculating critical point properties:
- Vm,c = 3b
- Tc = 8a /27bR
- Pc = a /27b2
Fugacity
-
Fugacity (f) is a measure of the escaping tendency of a real gas.
-
For an ideal gas, Æ’ = P.
-
Fugacity calculation:
- Z = 1 + A2P
- ln(fˉ\bar{f}fˉ​/Pi) = ∫0P $(\bar{V}{real} - \bar{V}{ideal}) dP / RT$
- Use the equation f = P´eA2P´ to calculate the fugacity.
