Chemistry - Real Gas Question with Solution | TestHub
Match Column I with Column II for a van der Waal's gas.
Column I | Column II |
|---|---|
A) Critical temperature | P) Depends upon nature of gas |
B) Free volume | Q) Constant for a particular gas |
C) Inversion temperature | R) Depends upon pressure for a particular gas |
D) Compressibility factor | S) Depends upon the radius of gas molecule |
Options:
Answer:
Solution:
Tc = 8a/27Rb is a fixed constant for a particular gas and depends on a and b, hence on the nature of the gas and molecular radius (b ∝ r³), so AP,Q,S. Free volume = V - nb: V changes with pressure for a given gas, and nb depends on the nature and size of the molecules, so BP,R,S. Tᵢ = 2a/Rb is a constant characteristic of the gas, depending on a, b and hence radius, so CP,Q,S. Z = PV/nRT varies with pressure for a given gas and with the gas (a, b; molecular size), so DP,R,S. Hence AP,Q,S; BP,R,S; CP,Q,S; DP,R,S.
