Match Column I with Column II for a van der Waal's gas.
Column I | Column II |
|---|---|
A) Free volume | P) Depends upon nature of gas |
B) Critical temperature | Q) Constant for a particular gas |
C) Boyle's temperature | R) Depends upon pressure for a particular gas |
D) Compressibility factor | S) Depends upon the radius of gas molecule |
Options:
Answer:
Solution:
Free volume = V - nb: V changes with pressure for a given gas, and b depends on the nature and size (radius) of the molecules, so A→P,R,S. 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 on molecular radius (through b ∝ r3), so B→P,Q,S. TB = a/Rb is likewise a constant characteristic of the gas, depending on a, b and hence radius, so C→P,Q,S. Z = PV/nRT varies with pressure for a given gas and with the gas (a, b; molecular size), so D→P,R,S. Hence A→P,R,S; B→P,Q,S; C→P,Q,S; D→P,R,S.
