Vedclass · Answer

(B) The compressibility factor $(Z)$ is defined as the ratio of the actual molar volume of a gas $(V_m)$ to the molar volume of an ideal gas $(V_{ideal})$ at the same temperature and pressure.For an ideal gas,the equation of state is $PV = nRT$. Thus,$V_{ideal} = \frac{nRT}{P}$.The compressibility factor is given by the formula $Z = \frac{PV}{nRT}$.For an ideal gas,$Z = 1$. For real gases,$Z 
eq 1$,which indicates the deviation from ideal behavior.

Which of the following formulae is used to determine the compressibility factor $(Z)$ for the measurement of deviation from ideal behavior?
