For a non-ideal gas, the compressibility factor `(Z)` is defined as:
`Z=(pV_(m))/(RT),V_(m)=` Molar volume
Compressibility of an unknown gas at `600K` and `1.0` atm was found to be 1.2 Also this gas was found to effuse 1.58 times slower than the pure methane gas under identical condition. Answer the following three questions based on the above mentioned information and the information provided in an individual question.
The value of the Virial coefficient `'B'` in the Virial equation is,
(Ignore the higher terms from equation during calculation)
Virial equation : `Z=1+B/(V_(m))+C/(V_(m)^(2))+D/(V_(m)^(3))+........., V_(m)` is the molar volume

Options

A. `8.16 L mol^(-1)`
B. `7.84Lmol^(-1)`
C. `11.76 mol^(-1)`
D. `5.44Lmol^(-1)`

Answer

C
