For one mole of a van der Waals gas, the compressibility factor

Z\left(=\frac{P V}{R T}\right)

at a fixed volume will certainly decrease if [Given: "a", "b" are standard parameters for van der Waals gas]

View answer and explanation

Correct option: B

b" decreases and "a" increases at constant temperature

Option B (b\" decreases and \"a\" increases at constant temperature) is correct because a larger 'a' (attraction) and smaller 'b' (repulsion) will decrease the compressibility factor Z.

If for the gases, the critical temperatures are mentioned below i.e.

\begin{array}{cccccccccccccccccccc} {\underline {{\text{Gas}}} }&{\underline {\,{\text{Critical}}\,\,{\text{temperature}}} } \\ {\text{A}}&{{T_{{C_1}}}} \\ {\text{B}}&{{T_{{C_2}}}} \\ {\text{C}}&{{T_{{C_3}}}} \\ {\text{D}}&{{T_{{C_4}}}} \end{array}

{T_{{C_1}}} > {T_{{C_2}}} > {T_{{C_3}}} > {T_{{C_4}}}
