(a) Inversely proportional to its absolute temperature

(b) Directly proportional to its absolute temperature

(c) Equal to the square of its absolute temperature

(d) All of the above

Correct order of van there Waals constant b for gases is CO₂ > N₂ > O₂ > H₂ > He

(A) Fluorspar                     –    CaF₂

(B) Cryolite                 –    Na₃ [AlF₆]

(C) Bauxite                 –    Al₂O₃.2H₂O

(D) Dolomite              –    MgCO₃.CaCO₃

Kindly go through the solution

Since V_Real > V_ideal

So, Z = V_Real > 1. V_ideal

The Answer is Maxwell? Boltzmann distribution

NH₃ can be liquefied most easily due to presence of strong intermolecular H-bonding among NH3 molecules.
