Statement I: Reduced equation of state in terms of reduce: temperature

\theta

, reduced volume

\phi

and reduced pressure x can be applied to solid, gases and liquid.

Statement II:

\left(\pi+\frac{3}{\phi^2}\right)(3 \phi-1)=8 \theta

. Equation is independent of

p, V

and

T

as well as independent of vander Waals' constant

a

and

b

View answer and explanation

Correct option: A

Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I

Option A is correct because the reduced equation of state applies to all states of matter, and the given equation is independent of specific gas constants.

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}}}
