Compressibility factor (Z) is given by
RT/PV
PV/RT
(RT/PV)2
(PV/RT)2
For an ideal gas, the compressibility factor (Z) value is
Z < 1
Z = 1
Z > 1
It depends to the P-V-T values
What assumptions are made for the ideal gas equation?
There is no attraction between the molecules of the gas.
The volume occupied by the molecules is negligible.
Both of the mentioned.
None of the mentioned.
In which condition can real gas obey closely the ideal gas equation?
Pressure is very small and temperature is very high.
Pressure is very high and temperature is very low.
Both pressure and temperature are very high.
Both pressure and temperature are very low.
Choose the correct form of van der Waals EoS:
(P+(a/V2)) (V+ b) = RT
(P + (a/V2)) (V– b) = RT
(P– (a/V2)) (V – b) = RT
(P – (a/V2)) (V+ b) = RT
Which of the following statement is true about the correction terms in vdW EoS?
"a" accounts for mutual attraction between the molecules.
The term a/(v2) is called the force of cohesion.
"b" accounts for the volumes of the molecules.
All of the mentioned.
Value of constant 'a' in vdW EoS increases with increase in:
intramolecular forces.
ionic bond.
intermolecular forces.
covalent bond.
"Any compound should have the same Z at the same reduced P and reduced T" is known as:
Law of corresponding states.
Law of critical state.
Law of reduced state.
Laws of thermodynamics.
Choose the FALSE statement for the second virial coefficient listed below:
It represents the deviation from ideal-gas behaviour.
The value needs to be determined at certain temperature.
It has the unit of (molar volume/temperature).
It has the same unit as molar volume.
